Yin Huai updated HIVE-5157:
---------------------------
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)
> ReduceSinkDeDuplication ignores hive.groupby.skewindata=true
