Review request for hive, John Sichi and Carl Steinbach.
Changes
-------
rebased to trunk
Summary
-------
If map aggregation is set to false, DISTRIBUTED BY followed by GROUP BY with
same key fails in runtime. ReduceSinkDeDuplication optimization should be avoid
if child of child RS is GBY.
This addresses bug HIVE-2329.
