Namit Jain resolved HIVE-10.
----------------------------

    Resolution: Fixed

Was fixed as part of the big merge.

Currently, we don't support general predicate push up However, if the predicate is present in the ON clause of the join, it is pushed up to the map stage

> Filter is not pushed above the join in Hive currently. This can be pretty expensive if the filter is highly selective.
