      Description

      ISSUE: Queries fail when execution engine is Tez from Hive view.

      Error :

      java.lang.NullPointerException

      The same query works in the hive view if the execution engine is MR.

      Restarting Ambari did not work. Here is the tail of the ambari-server log:
