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

             Summary: Remove predicate on partition columns from Table Scan operator
                 Key: HIVE-21599
                 URL: https://issues.apache.org/jira/browse/HIVE-21599
             Project: Hive
          Issue Type: Improvement
          Components: Query Planning
            Reporter: Vineet Garg
            Assignee: Vineet Garg


Filter predicates are pushed to Table Scan (to be pushed to and used by storage handler/input format). Such predicates could consist of partition columns which are of no use to storage handler  or input formats. Therefore it should be removed from TS filter expression.
