Configuring HDFS for Files View
You need to set up an HDFS proxy user for the Ambari daemon account. For example, if
ambari-server daemon is runnng as root
, you set up a proxy user for
root
in core-site by adding and changing properties in HDFS > Configs >
Custom core-site:
hadoop.proxyuser.root.groups=*
hadoop.proxyuser.root.hosts=*
Restart the required components as indicated by Ambari. If you want to add multiple views, you can restart services once, after making changes for all views.

If Ambari Server is running as a non-root user, such as 'ambari', and you are planning on using Ambari Views, the following properties in Services > HDFS > Configs > Advanced core-site must be added: hadoop.proxyuser.ambari.groups=* hadoop.proxyuser.ambari.hosts=* See the Ambari Security Guide for more information about How to Configure Ambari Server for Non-Root. |

This view stores user metadata in HDFS. By default, the location in HDFS for this metadata is
su - hdfs hadoop fs -mkdir /user/admin hadoop fs -chown admin:hadoop /user/admin
