Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application. Creating a JDBC data source based on the CData JDBC Driver for Spark SQL consists of three basic steps:

• Add the driver JAR file to the classpath. The JAR file is located in the lib subfolder of the installation directory. Note that the .lic file must be located in the same folder as the JAR file.
• Provide the driver class. For example:
  

  cdata.jdbc.sparksql.SparkSQLDriver

• Provide the JDBC URL. For example:
  

  jdbc:sparksql:Server=127.0.0.1;
  
  or
  
  jdbc:cdata:sparksql:Server=127.0.0.1;

  The second format above can be used whenever there is a conflict in your application between drivers using the same URL format to ensure you are using the CData driver. The URL must start with either "jdbc:sparksql:" or "jdbc:cdata:sparksql:" and can include any of the connection properties in name-value pairs separated with semicolons.

Connecting to Spark SQL

Specify the following to establish a connection with Spark SQL:

• Server: The host name or IP address of the server hosting SparkSQL.
• Port: The port for the connection to the SparkSQL instance.
• TransportMode: The transport mode to use to communicate with the SparkSQL server. Accepted entries are BINARY and HTTP. BINARY is selected by default.

Securing Spark SQL Connections

To enable TLS/SSL in the driver, set UseSSL to True.

Authenticating to Spark SQL

The service may be authenticated to using the PLAIN, LDAP, NOSASL, KERBEROS auth schemes.

PLAIN

To authenticate with PLAIN, set the following connection properties:

• AuthScheme: PLAIN.
• User: The user to login as.
• Password: The password of the user.

To authenticate, set User and Password.

LDAP

To authenticate with LDAP, set the following connection properties:

• AuthScheme: LDAP.
• User: The user to login as.
• Password: The password of the user.

To authenticate, set User, Password, and AuthScheme.

NOSASL

When using NOSASL, no authentication is performed. Set the following connection properties:

• AuthScheme: NOSASL.

Kerberos
