Step 2. Configure the Ranger and DAS Databases
If you plan to use Data Analytics Studio or Ranger in a trial cluster, you must create DAS and Ranger databases.
If you plan to use Ranger during the trial, you must create a Ranger database. A script is provided to create the database.
Complete this task before you setup a cluster with Ranger enabled:
To create the Ranger database, run the
/opt/cloudera/cm/binon the Cloudera Manager host.The output of the script gives you the default Ranger database host, default database name, default database user, and the Ranger database user password to use during cluster setup.
- Take note of the script output. Although the database name and database user are default values, you will need to enter the host and Ranger database user password on the Enter Required Parameters page when you configure a cluster.
If cluster deployment fails, be sure to click Resume in the wizard after you fix any issues. If you do not click Resume, the Ranger service will not enable all of the necessary plugins.
