Subject [jira] Updated: (HIVE-1538) FilterOperator is applied twice with ppd on.
Date Wed, 24 Nov 2010 04:59:15 GMT

     [ https://issues.apache.org/jira/browse/HIVE-1538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
