4. Collect Information

To deploy your HDP installation, you need to collect the following information:

  • The network resolvable name for each host in your cluster. This can be the IP address or the hostname.

    To determine the hostname for a particular cluster host, open the command shell on that cluster host and execute hostname.


    The installer will fail if it cannot resolve the hostname of each cluster node.

  • (Optional): To be able to use an external database for Hive or Oozie metastore, ensure that you have the hostname (for an existing instance), database name, and user account credentials for the SQL Server instance.


    Create two database users, ooziemetastore and hivemetastore, in SQL Server and assign the following database roles to each: db_datareader, db_datawriter, db_ddladmin, and public.
