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

Minimum macOS Version

The CData ODBC Driver for HDFS 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 HDFS/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 HDFS

In order to connect, set the following connection properties:

• Host: Set this value to the host of your HDFS installation.
• Port: Set this value to the port of your HDFS installation. Default port: 50070
• UseSSL: (Optional) Set this value to 'True', to negotiate TLS/SSL connections to the HDFS server. Default: 'False'.

Authenticating to HDFS

There are two authentication methods available for connecting to the HDFS data source, Anonymous Authentication and Negotiate (Kerberos) Authentication.

Anonymous Authentication

In some situations, HDFS may be connected to without any authentication connection properties. To do so, set the AuthScheme to None (default).

Kerberos

When authentication credentials are required, you can use Kerberos. See Using Kerberos for details on how to authenticate with Kerberos.

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 HDFS"
sudo ./uninstall.sh

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