Amareshwari Sriramadasu commented on HIVE-1538:
-----------------------------------------------

John, I modified the existing ppd_* tests to run with new configuration on and off. I copied
the queries as they are and did not modify the the statements at all. If you are keen adding
order by to the queries, Will do. I'd like to do in a follow up and not stop this patch.

operator is always filtering zero rows.
