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 HBase

The HBase Adapter connects to Apache HBase via the HBase REST (Stargate) server. Set the following to connect to HBase:

• Server: This will typically be the host name or IP address of the server hosting 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 HBase REST (Stargate) server.

Authenticating to HBase

The HBase Adapter 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 HBase user.
• Password: Set this to the 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.
