Amareshwari Sriramadasu updated HIVE-1538:
------------------------------------------
Attachment: patch-1538.txt
Patch with following changes:
* creates a filter operator with unpushed predicates, as a child of the
operator through which the predicates could not be pushed.
* removes original filter operator if it does not have any non-final
candidates.
With creating a child filter operator with the non-final candidates and
removing the original one, I'm seeing some problems. So, would like to do that
in a followup jira.
* Updates all the tests with new explain plans.
> FilterOperator is applied twice with ppd on.
