Configure your cluster for Pig View

For Pig View to access HDFS, the Ambari Server daemon hosting the view must act as the proxy user for HDFS.

This allows Ambari to submit requests to HDFS on behalf of the users using the Pig View. This is critical since Pig View will store metadata about the user Pig scripts. This also means users that will access Pig View must have a user directory setup in HDFS. In addition, Pig View uses WebHCat to submit Pig scripts so the View needs a proxy user for WebHCat.

If you are running views in an operational Ambari server (one that is operating the cluster) Ambari does this setup by default. You should verify that the HDFS and WebHCat proxy user and the HDFS user directory settings are correct. If you are running views on a standalone server, you must setup proxy user settings manually.
