Install the Prerequisite Components and Services

You need an Ambari cluster with the following components and services to install and use DAS: YARN, HDFS, Hive, and Knox and Ranger for secure clusters.

Set up a cluster managed by Ambari that includes at least the following components and services: YARN, HDFS, Hive.

Configure Knox and Ranger if you choose to set up secure clusters.

To install Ambari and the related services, see Installing Ambari in the Apache Ambari Installation Guide.
(For secure clusters) Configure Knox SSO for Ambari, Hive, and Ranger. See Setting up Knox SSO.
After you set up and enable Knox SSO through the Ambari CLI, test whether you have configured it correctly by using the following steps:
1. Sign out from Ambari.
  
  You should be redirected to the Knox SSO login page.
2. Sign in using your credentials.
  
  You should be able to log in using your credentials.
