Description

When running multi-insert queries, when one of the query is not returning results, the other query is not returning the right result.
For example:
After following query, there is no value in /tmp/emp/dir3/000000_0

From (select * from src) a
insert overwrite directory '/tmp/emp/dir1/'
select key, value
insert overwrite directory '/tmp/emp/dir2/'
select 'header'
where 1=2
insert overwrite directory '/tmp/emp/dir3/'
select key, value 
where key = 100;

where clause in the second insert should not affect the third insert.
