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

Minimum macOS Version

The CData ODBC Driver for Apache HBase 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 Apache HBase/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.

Before You Connect

Different Hadoop distributions contain different interfaces and means of starting and stopping the HBase REST server, along with different default port settings.

In most distributions, the HBase REST server can be started in the foreground by running the following command: hbase rest start -p <port>.

Please consult your Hadoop distribution's documentation for further information regarding the HBase REST server.

Connecting to Apache HBase

The CData ODBC Driver for Apache HBase connects to Apache HBase via the HBase REST (Stargate) server. Set the following to connect to Apache HBase:

• Server: This will typically be the host name or IP address of the server hosting Apache HBase. If there are multiple nodes, use the host name or IP address of the machine running the REST (Stargate) server.
• Port: Set this to the port for the Apache HBase REST (Stargate) server.

Authenticating to Apache HBase

The CData ODBC Driver for Apache HBase supports the following authentication schemes:

• Anonymous
• Basic
• Negotiate (Kerberos)

Anonymous

By default, no authentication (alternatively known as "anonymous" authentication) is used. Set AuthScheme to None to explicitly enforce no authentication.

Basic

To use Basic authentication, set the following:

• AuthScheme: Set this to Basic.
• User: Set this to the Apache HBase user.
• Password: Set this to the Apache HBase password.

Kerberos

To authenticate with Kerberos, set AuthScheme to NEGOTIATE and set the User and Password. Please 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 Apache HBase"
sudo ./uninstall.sh

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