Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
3. Click the System DSN tab.
4. Select the system data source and click Configure.
5. Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

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.
