The CData Sync App provides a straightforward way to continuously pipeline your Apache Hive data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.
The Apache Hive connector can be used from the CData Sync application to pull data from Apache Hive and move it to any of the supported destinations.
The Sync App models Apache Hive instances as relational databases. Hive versions 0.11.0 and above are supported. The Sync App leverages the HiveServer2 Thrift API, to enable bidirectional access to Apache Hive data through SQL.
For required properties, see the Settings tab.
For connection properties that are not typically required, see the Advanced tab.

To authenticate to Apache Hive with PLAIN SASL, set the hive.server2.authentication property in your Hive configuration file (hive-site.xml) to None and set the following Sync App connection properties:
To authenticate to Apache Hive with Kerberos, set AuthScheme to KERBEROS.
Authenticating to Apache Hive via Kerberos requires you to define authentication properties and to choose how Kerberos should retrieve authentication tickets.
The Sync App provides three ways to retrieve the required Kerberos ticket, depending on whether or not the KRB5CCNAME and/or KerberosKeytabFile variables exist in your environment.
MIT Kerberos Credential Cache File
This option enables you to use the MIT Kerberos Ticket Manager or kinit command to get tickets. With this option there is no need to set the User or Password connection properties.
This option requires that KRB5CCNAME has been created in your system.
To enable ticket retrieval via MIT Kerberos Credential Cache Files:
If the ticket is successfully obtained, the ticket information appears in Kerberos Ticket Manager and is stored in the credential cache file.
The Sync App uses the cache file to obtain the Kerberos ticket to connect to Apache Hive.
Note: If you would prefer not to edit KRB5CCNAME, you can use the KerberosTicketCache property to set the file path manually. After this is set, the Sync App uses the specified cache file to obtain the Kerberos ticket to connect to Apache Hive.
Keytab File
If your environment lacks the KRB5CCNAME environment variable, you can retrieve a Kerberos ticket using a Keytab File.
To use this method, set the User property to the desired username, and set the KerberosKeytabFile property to a file path pointing to the keytab file associated with the user.
User and Password
If your environment lacks the KRB5CCNAME environment variable and the KerberosKeytabFile property has not been set, you can retrieve a ticket using a user and password combination.
To use this method, set the User and Password properties to the user/password combination that you use to authenticate with Apache Hive.
To enable this kind of cross-realm authentication, set the KerberosRealm and KerberosKDC properties to the values required for user authentication. Also, set the KerberosServiceRealm and KerberosServiceKDC properties to the values required to obtain the service ticket.
Apache Hive supports multiple ways to perform similar operations. The options below allow you to configure which HiveQL statement is issued to perform an operation.
When set to true, the Sync App will perform INSERT queries using the INSERT INTO SELECT syntax: INSERT INTO TABLE [table] SELECT T.* FROM (....) AS T.
If set to false (default), the INSERT INTO VALUES syntax will be used: INSERT INTO TABLE [table] VALUES (....).
The Sync App will automatically determine which syntax is supported by your Hive server but setting this option to true will force the INSERT INTO SELECT syntax to be used.
This section details a selection of advanced features of the Apache Hive Sync App.
The Sync App supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .
Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .
Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.
For further information, see Query Processing.
To enable TLS, set UseSSL to True.
With this configuration, the Sync App attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.
To specify another certificate, see the SSLServerCert connection property.
To authenticate to an HTTP proxy, set the following:

Specifies the TLS/SSL client certificate store for SSL Client Authentication (2-way SSL). This property works in conjunction with other SSL-related properties to establish a secure connection.
This property specifies the client certificate store for SSL Client Authentication. Use this property alongside SSLClientCertType, which defines the type of the certificate store, and SSLClientCertPassword, which specifies the password for password-protected stores. When SSLClientCert is set and SSLClientCertSubject is configured, the driver searches for a certificate matching the specified subject.
Certificate store designations vary by platform. On Windows, certificate stores are identified by names such as MY (personal certificates), while in Java, the certificate store is typically a file containing certificates and optional private keys.
The following are designations of the most common User and Machine certificate stores in Windows:
| MY | A certificate store holding personal certificates with their associated private keys. |
| CA | Certifying authority certificates. |
| ROOT | Root certificates. |
| SPC | Software publisher certificates. |
For PFXFile types, set this property to the filename. For PFXBlob types, set this property to the binary contents of the file in PKCS12 format.

Specifes the password required to access the TLS/SSL client certificate store. Use this property if the selected certificate store type requires a password for access.
This property provides the password needed to open a password-protected certificate store. This property is necessary when using certificate stores that require a password for decryption, as is often recommended for PFX or JKS type stores.
If the certificate store type does not require a password, for example USER or MACHINE on Windows, this property can be left blank. Ensure that the password matches the one associated with the specified certificate store to avoid authentication errors.
Specifes the subject of the TLS/SSL client certificate to locate it in the certificate store. Use a comma-separated list of distinguished name fields, such as CN=www.server.com, C=US. The wildcard * selects the first certificate in the store.
This property determines which client certificate to load based on its subject. The Sync App searches for a certificate that exactly matches the specified subject. If no exact match is found, the Sync App looks for certificates containing the value of the subject. If no match is found, no certificate is selected.
The subject should follow the standard format of a comma-separated list of distinguished name fields and values. For example, CN=www.server.com, OU=Test, C=US. Common fields include the following:
| Field | Meaning |
| CN | Common Name. This is commonly a host name like www.server.com. |

The authentication method used when establishing an SSH Tunnel to the service.
A certificate to be used for authenticating the SSHUser.
SSHClientCert must contain a valid private key in order to use public key authentication. A public key is optional, if one is not included then the Sync App generates it from the private key. The Sync App sends the public key to the server and the connection is allowed if the user has authorized the public key.
The SSHClientCertType field specifies the type of the key store specified by SSHClientCert. If the store is password protected, specify the password in SSHClientCertPassword.
Some types of key stores are containers which may include multiple keys. By default the Sync App will select the first key in the store, but you can specify a specific key using SSHClientCertSubject.
The password of the SSHClientCert key if it has one.
This property is required for SSH tunneling when using certificate-based authentication. If the SSH certificate is in a password-protected key store, provide the password using this property to access the certificate.
The subject of the SSH client certificate.
When loading a certificate the subject is used to locate the certificate in the store.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks the first certificate in the certificate store.
The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, [email protected]". Common fields and their meanings are displayed below.
| Field | Meaning |
| CN | Common Name. This is commonly a host name like www.server.com. |
| O | Organization |

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.
| Property | Description |
| FirewallType | Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall. |
| FirewallServer | Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources. |
| FirewallPort | Specifies the TCP port to be used for a proxy-based firewall. |
| FirewallUser | Identifies the user ID of the account authenticating to a proxy-based firewall. |
| FirewallPassword | Specifies the password of the user account authenticating to a proxy-based firewall. |
Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.
Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.
Note: By default, the Sync App connects to the system proxy. To disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.
The following table provides port number information for each of the supported protocols.
| Protocol | Default Port | Description |
| TUNNEL | 80 | The port where the Sync App opens a connection to Apache Hive. Traffic flows back and forth via the proxy at this location. |
| SOCKS4 | 1080 | The port where the Sync App opens a connection to Apache Hive. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted. |
| SOCKS5 | 1080 | The port where the Sync App sends data to Apache Hive. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes. |
To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.
Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.
A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.
Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.
Specifies the TCP port to be used for a proxy-based firewall.

This section provides a complete list of the Proxy properties you can configure in the connection string for this provider.
| Property | Description |
| ProxyAutoDetect | Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server. |
| ProxyServer | The hostname or IP address of the proxy server that you want to route HTTP traffic through. |
| ProxyPort | The TCP port on your specified proxy server (set in the ProxyServer connection property) that has been reserved for routing HTTP traffic to and from the client. |
| ProxyAuthScheme | Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property. |
| ProxyUser | The username of a user account registered with the proxy server specified in the ProxyServer connection property. |
| ProxyPassword | The password associated with the user specified in the ProxyUser connection property. |
| ProxySSLType | The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property. |
| ProxyExceptions | A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property. |
Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.
When this connection property is set to True, the Sync App checks your system proxy settings for existing proxy server configurations (no need to manually supply proxy server details).
This connection property takes precedence over other proxy settings. Set to False if you want to manually configure the Sync App to connect to a specific proxy server.
To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.
The hostname or IP address of the proxy server that you want to route HTTP traffic through.
The Sync App only routes HTTP traffic through the proxy server specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server specified in your system proxy settings.
The TCP port on your specified proxy server (set in the ProxyServer connection property) that has been reserved for routing HTTP traffic to and from the client.
The Sync App only routes HTTP traffic through the proxy server port specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server port specified in your system proxy settings.
For other proxy types, see FirewallType.
Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.
The authentication type can be one of the following:
For all values other than "NONE", you must also set the ProxyUser and ProxyPassword connection properties.
If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.
The username of a user account registered with the proxy server specified in the ProxyServer connection property.
The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.
After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:
| ProxyAuthScheme Value | Value to set for ProxyUser |
| BASIC | The user name of a user registered with the proxy server. |
| DIGEST | The user name of a user registered with the proxy server. |
| NEGOTIATE | The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user. |
| NTLM | The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user. |
| NONE | Do not set the ProxyPassword connection property. |
The Sync App only uses this username if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the username specified in your system proxy settings.
The password associated with the user specified in the ProxyUser connection property.
The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.
After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:
| ProxyAuthScheme Value | Value to set for ProxyPassword |
| BASIC | The password associated with the proxy server user specified in ProxyUser. |
| DIGEST | The password associated with the proxy server user specified in ProxyUser. |
| NEGOTIATE | The password associated with the Windows user account specified in ProxyUser. |
| NTLM | The password associated with the Windows user account specified in ProxyUser. |
| NONE | Do not set the ProxyPassword connection property. |
For SOCKS 5 authentication or tunneling, see FirewallType.
The Sync App only uses this password if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the password specified in your system proxy settings.
The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.
This property determines when to use SSL for the connection to the HTTP proxy specified by ProxyServer. You can set this connection property to the following values :
| AUTO | Default setting. If ProxyServer is set to an HTTPS URL, the Sync App uses the TUNNEL option. If ProxyServer is set to an HTTP URL, the component uses the NEVER option. |
| ALWAYS | The connection is always SSL enabled. |
| NEVER | The connection is not SSL enabled. |
| TUNNEL | The connection is made through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy. |
A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.
The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.
Note that the Sync App uses the system proxy settings by default, without further configuration needed. If you want to explicitly configure proxy exceptions for this connection, set ProxyAutoDetect to False.
This section provides a complete list of the Logging properties you can configure in the connection string for this provider.
| Property | Description |
| LogModules | Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged. |
Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.
This property lets you customize the log file content by specifying the logging modules to include. Logging modules categorize logged information into distinct areas, such as query execution, metadata, or SSL communication. Each module is represented by a four-character code, with some requiring a trailing space for three-letter names.
For example, EXEC logs query execution, and INFO logs general provider messages. To include multiple modules, separate their names with semicolons as follows: INFO;EXEC;SSL.
The Verbosity connection property takes precedence over the module-based filtering specified by this property. Only log entries that meet the verbosity level and belong to the specified modules are logged. Leave this property blank to include all available modules in the log file.
For a complete list of available modules and detailed guidance on configuring logging, refer to the Advanced Logging section in Logging.
This section provides a complete list of the Schema properties you can configure in the connection string for this provider.
| Property | Description |
| Location | Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path. |
| BrowsableSchemas | Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC . |
| Tables | Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC . |
| Views | Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC . |
Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is %APPDATA%\\CData\\ApacheHive Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:
| Platform | %APPDATA% |
| Windows | The value of the APPDATA environment variable |
| Linux | ~/.config |
Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.
Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.
If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.
Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .
Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.
If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views. To do this, specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| AsyncQueryTimeout | The timeout for asynchronous requests issued by the provider to download large result sets. |
| EnableXSRF | This option specifies whether to add the X-XSRF-Header filter to HiveServer2 HTTP mode. |
| FailoverHosts | This property allows you to specify a list of failover hosts in addition to the one configured in Server and Port . |
| HTTPPath | The path component of the URL endpoint when using HTTP TransportMode. |
| JGSSPrincipalAsDBUser | Whether to use the Kerberos principal as the database username. Only applies when UseJGSS is enabled. |
| MaxRows | Specifies the maximum rows returned for queries without aggregation or GROUP BY. |
| Other | Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties. |
| Pagesize | Specifies the maximum number of results to return from Apache Hive, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property. |
| QueryPassthrough | This option passes the query to the Apache Hive server as is. |
| ServerConfigurations | A list of server configuration variables to override the server defaults. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout. |
| UseDescTableQuery | This option specifies whether the columns will be retrieved using a DESC TABLE query or the GetColumns Thrift API. |
| UseJGSS | Specify whether to use native Java Kerberos Authentication (JGSS) for Kerberos Authentication. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file. |
| UseShowDatabasesQuery | This option specifies whether the schemas will be retrieved using a SHOW DATABASES query or the GetSchemas Thrift API. |
| UseShowTablesQuery | This option specifies whether the tables will be retrieved using a SHOW TABLES query or the GetTables Thrift API. |
| UseSSL | Specifies whether to use SSL Encryption when connecting to Hive. |
| UseZookeeperDiscovery | Specifies whether to use ZooKeeper Service Discovery. |
| ZookeeperNamespace | The namespace configured on ZooKeeper for the Hive Server 2 znodes. |
The timeout for asynchronous requests issued by the provider to download large result sets.
If the AsyncQueryTimeout property is set to 0, asynchronous operations will not time out; instead, they will run until they complete successfully or encounter an error condition. This property is distinct from Timeout which applies to individual operations while AsyncQueryTimeout applies to execution time of the operation as a whole.
If AsyncQueryTimeout expires and the asynchronous request has not finished being processed, the Sync App raises an error condition.
This option specifies whether to add the X-XSRF-Header filter to HiveServer2 HTTP mode.
This option specifies whether to add the X-XSRF-Header filter to HiveServer2 HTTP mode.
This property allows you to specify a list of failover hosts in addition to the one configured in Server and Port .
Specify both a server and port with multiple values separated with commas. For example 'server1:port1,server2,port2'.
The Server and Port values take precedence and will be used to make the initial connection. Upon a failure to connect to the main host, the list of FailoverHosts will be used to attempt the connection.
The path component of the URL endpoint when using HTTP TransportMode.
This property is used to specify the path component of the URL endpoint when using HTTP TransportMode.
This property should be set to the value specified in the 'hive.server2.thrift.http.path' property of you Hive configuration file (hive-site.xml).
Whether to use the Kerberos principal as the database username. Only applies when UseJGSS is enabled.
The Sync App uses three pieces of information to authenticate the connection in Kerberos mode. When UseJGSS is enabled, only the service principal and database role may be configured within the Sync App. The user principal comes from the subject configured inside the Java security framework.
By default the KerberosUser (or User) is the service principal. The database user is automatically derived from the user principal. For example, if you authenticate as the user principal [email protected] the database user is set to bob.
When JGSSPrincipalAsDBUser=false, the KerberosUser (or User) is the database role and the KerberosSPN is the service principal.
Specifies the maximum rows returned for queries without aggregation or GROUP BY.
This property sets an upper limit on the number of rows the Sync App returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.
When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.
This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.
Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.
This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.
Note: It is strongly recommended to set these properties only when advised by the support team to address specific scenarios or issues.
Specify multiple properties in a semicolon-separated list.
| DefaultColumnSize | Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
| ConvertDateTimeToGMT | Determines whether to convert date-time values to GMT, instead of the local time of the machine. |
| RecordToFile=filename | Records the underlying socket data transfer to the specified file. |
Specifies the maximum number of results to return from Apache Hive, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases.
You may want to adjust the default pagesize to optimize results for a particular object or service endpoint you are querying. Be aware that increasing the page size may improve performance, but it could also result in higher memory consumption per page.
Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
This property allows you to define which pseudocolumns the Sync App exposes as table columns.
To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"
To include all pseudocolumns for all tables use: "*=*"
This option passes the query to the Apache Hive server as is.
When this is set, queries are passed through directly to Apache Hive.
A list of server configuration variables to override the server defaults.
This property takes a comma-separated list of Hive configuration variables. Each value in the comma-separated list will be sent as specified to the Hive server via the 'set' command to override the server default values.
Example: hive.enforce.bucketing=true,hive.enforce.sorting=true
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
This property controls the maximum time, in seconds, that the Sync App waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the Sync App cancels the operation and throws an exception.
The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.
Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.
This option specifies whether the columns will be retrieved using a DESC TABLE query or the GetColumns Thrift API.
When set to true, a DESC TABLE query will be issued to retrieve the columns for the table.
Specify whether to use native Java Kerberos Authentication (JGSS) for Kerberos Authentication.
By default the Sync App uses an internal Kerberos implementation. Enabling this option makes it use Kerberos credentials attached to the current security Subject. The Sync App uses impersonation credentials if they are available (from Subject.getPrivateCredentials), otherwise the Subject's normal credentials are used.
Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.
This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:
{
"MyView": {
"query": "SELECT * FROM [CData].[Default].Customers WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the Sync App.
Refer to User Defined Views for more information.
This option specifies whether the schemas will be retrieved using a SHOW DATABASES query or the GetSchemas Thrift API.
When set to true, a SHOW DATABASES query will be issued to retrieve the schemas.
This option specifies whether the tables will be retrieved using a SHOW TABLES query or the GetTables Thrift API.
When set to true, a SHOW TABLES query will be issued to retrieve the tables for the database.
Specifies whether to use SSL Encryption when connecting to Hive.
Set this property to the value specified in the 'hive.server2.use.SSL' property of your Hive configuration file (hive-site.xml).
Specifies whether to use ZooKeeper Service Discovery.
When set to 'True', Hive servers will be discovered via the ZooKeeper service.
The Server and Port must be set to the configured ZooKeeper server and port. The ZookeeperNamespace property must be set to the namespace configured on ZooKeeper for the Hive Server 2 znodes.
If multiple ZooKeeper servers are available, FailoverHosts can be set to the additional ZooKeeper instances.
The namespace configured on ZooKeeper for the Hive Server 2 znodes.
This property is only applicable when UseZookeeperDiscovery is set to 'True'.
