> On HIVE-16415, it was found that the bug reported to be fixed in HIVE-14519 was not actually
fixed.
> This task is to find the problem, fix it, and add qtests to verify no future regression.
> Specifically, the following query does not produce correct answers: 
> {code}
> From (select * from src) a
> insert overwrite directory '/tmp/emp/dir1/'
> select key, value
> insert overwrite directory '/tmp/emp/dir2/'
> select 'header'
> limit 0
> insert overwrite directory '/tmp/emp/dir3/'
> select key, value 
> where key = 100;
> {code}
> This gives incorrect result in master. All dirs end up with 0 rows instead of just dir2.
