Creating MRS Hive Data Connections

Before establishing a data connection to MapReduce (MRS) Hive, ensure that the following conditions are met:

  • An MRS cluster earlier than 2.0.0 has been created. The cluster contains Hive components. Kerberos authentication has been disabled for the MRS cluster. DLV does not support MRS Hive data sources with Kerberos authentication enabled.
  • You have obtained the MRS Hive address.

Creating an MRS Hive Data Connection

  1. Log in to the DLV console.
  2. On the Data page, click the workspace drop-down list at the top of the page, select the workspace to be accessed, and click New Data Connection.
