ADO.NET Provider for Apache HBase

Build 21.0.7930

Establishing a Connection

Connecting to Apache HBase

The CData ADO.NET Provider for Apache HBase connects to Apache HBase via the HBase REST (Stargate) server. Set the Port and Server properties to connect to Apache HBase.

The Server property will typically be the host name or IP address of the server hosting Apache HBase. If there are multiple nodes, you will use the host name or IP address of the machine running the REST (Stargate) server.

Starting the Server

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.

Authenticating to Apache HBase

The CData ADO.NET Provider for Apache HBase supports authentication over Basic and Negotiate.

No Authentication

By default, no authentication (or anonymous auth) is used. Set AuthScheme to None to explicitly enforce no authentication.

Authenticating with Basic

Basic authentication may be used by setting AuthScheme to Basic. In addition, set the following:

  • User: The Apache HBase user;
  • Password: The Apache HBase password;

Authenticating with 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.
