Jian Fang commented on HIVE-5888:
---------------------------------
Also tried to set hive.optimize.skewjoin=true and hive.auto.convert.join=false
for the patched Hive-0.11, but still got the "two long running reducers" issue.
How to solve this issue then?
> group by after join operation product no result when hive.optimize.skewjoin
