> 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
> {noformat}
> 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;
> {noformat}
> where clause in the second insert should not affect the third insert.
