Configuring Specific Ambari Views
Also available as:

Set up HDFS proxy user

To set up an HDFS proxy user for the Ambari Server daemon account, you must configure the proxy user in the HDFS configuration.

If you previously set up the proxy user for another View, you can skip this task.
This configuration is determined by the account name the ambari-server daemon is running as. For example, if your ambari-server is running as root, you set up an HDFS proxy user for root.
  1. In Ambari Web, browse to Services > HDFS > Configs.
  2. On the Advanced tab, navigate to the Custom core-site section.
  3. Click Add Property…, then add the following custom properties:
    Notice the ambari-server daemon account name root is part of the property name. Be sure to modify this property name for the account name you are running the ambari-server as. For example, if you were running ambari-server daemon under an account name of ambariusr, you would use the following properties instead.
    Similarly, if you have configured Ambari Server for Kerberos, be sure to modify this property name for the primary Kerberos principal user. For example, if ambari-server is setup for Kerberos using principal ambari-server@EXAMPLE.COM, you would use the following properties instead:
  4. Save the configuration change.
Restart the required components as prompted by Ambari.
