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.

> right now if one hive query got compiled to 2 mr jobs, and the first job's output feed
the second job. When the query finish, the first job's output should be removed.
