---------------------------
Description: If hive.groupby.skewindata=true, we should generate two MR jobs. But, ReduceSinkDeDuplication will merge these two into a single MR job. Example: groupby2_map_skew.q and groupby2.q (was: If hive.groupby.skewindata=true, we should generate two MR jobs. But, ReduceSinkDeDuplication will merge these two into a single MR job. Example: groupby2_map_skew.q)
