Priyadarshini commented on HIVE-2422:
-------------------------------------
I have executed this query.
select a.rollNo,b.rollNo from student a join student b on a.rollNo=b.rollNo
group by a.rollNo,b.rollNo;
The above query has spawned 2 MR jobs.
After the execution of the query, org.apache.hadoop.hive.ql.Context.clear()
method is deleting the ScratchDir of the query.
> remove the intermediate dir when the hive query finish
