Amareshwari Sriramadasu updated HIVE-1534:
------------------------------------------
Attachment: patch-1534.txt
I worked on separating filters for outer joins.
Here is a patch which does not push filters for outer joins and filters are
applied in the join implementation.
Patch would need some more work on SMBMapJoin. Please have look if the approach
looks fine.
> Join filters do not work correctly with outer joins
