This section shows how to set up ODBC connectivity and configure DSNs on macOS.

Minimum macOS Version

The CData ODBC Driver for Spark SQL driver requires macOS Sierra (10.12) or above.

Licensing the Driver

In a terminal, run the following commands to license the driver. To activate a trial, omit the <key> input.

cd "/Applications/CData ODBC Driver for Spark SQL/bin"
sudo ./install-license.sh <key>

You'll be prompted for a name and password. These refer to your name and your machine's password.

Connecting to Spark SQL

Specify the following to establish a connection with Spark SQL:

• Server: Set this to the host name or IP address of the server hosting SparkSQL.
• Port: Set this to 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: Set this to PLAIN.
• User: Set this to user to login as.
• Password: Set this to the password of the user.

To authenticate, set User and Password.

LDAP

• Password: Set this to 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: Set this to NOSASL.

Kerberos

Please see Using Kerberos for details on how to authenticate with Kerberos.

Connecting to Databricks

To connect to a Databricks cluster, set the properties as described below. Note: The needed values can be found in your Databricks instance by navigating to 'Clusters', selecting the desired cluster, and selecting the JDBC/ODBC tab under 'Advanced Options'.

• Server: Set to the Server Hostname of your Databricks cluster.
• Port: 443
• TransportMode: HTTP
• HTTPPath: Set to the HTTP Path of your Databricks cluster.
• UseSSL: True
• AuthScheme: PLAIN
• User: Set this to user to login as
• Password: Set to your personal access token (value can be obtained by navigating to the User Settings page of your Databricks instance and selecting the Access Tokens tab).

Uninstalling the Driver

The easiest way to uninstall the driver is to open a terminal and run the included uninstall.sh script, located in the installation directory. For example:

cd "/Applications/CData ODBC Driver for Spark SQL"
sudo ./uninstall.sh

Note: The script needs to be run from the installation directory.
