Review request for hive and Ashutosh Chauhan.


Repository: hive-git


Description
-------

In StatsOptimizer with return path on, we may have aggr($f0), aggr($f1) in GBY
and then select aggr($f1), aggr($f0) in SEL.
Thus we need to use colExp to find out which position is
corresponding to which position.
