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.
    https://issues.apache.org/jira/browse/HIVE-2329
