Laljo John Pullokkaran commented on OPTIQ-438:
----------------------------------------------
The patch has two aspects:
1. It enables pushing of predicate through SemiJoin
2. It allows customization of Predicate Push Down Logic
Hive only allows equality predicates and functions that refer to only child
of Join in ON clause.
I discussed this with you and i thought we agreed on this strategy.
I can modify the patch to add unit test.
