Prasanth J updated HIVE-8580:
-----------------------------
    Attachment: HIVE-8580.1.patch

This patch must go in after HIVE-8584 is committed. I will run the lateral view q tests once
HIVE-8584 is committed. Will make patch available after that.

> HIVE-8454 showed some test failures related to lateral view stats showing data size as
0. The reason for that is column expression map for LateralViewForwardOperator is not populated
which results column lists becoming empty. As a result neededColumns and referencedColumns
will be empty. Hence no column stats will be fetched making data size as 0.
