-----------------------------------

             Summary: Fix Optimization order for RewriteGBUsingIndex
                 Key: HIVE-7007
                 URL: https://issues.apache.org/jira/browse/HIVE-7007
             Project: Hive
          Issue Type: Bug
            Reporter: Harish Butani

This is a regression for Queries where Index tables replace the original table. See HIVE-7006

Capturing this here, at some point we should fix this. Ideally we should move ColumnPruner
back to its original position.
