["Amareshwari Sriramadasu (JIRA)" <ji...@apache.org>]

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.

> With hive.optimize.ppd set to true, FilterOperator is applied twice. And it seems second operator is always filtering zero rows.
