Sorry. This is a duplicate of TAJO-226. Apache JIRA too slow, so submitted several times.

> I ran the bellow query which uses column alias and group by.
> {code}
> select b.n_name as nation, count(*) as cnt
>   from customer_100 a, nation_100 b 
>  where a.c_nationkey = b.n_nationkey 
>  group by b.n_name
>  order by cnt desc
>  limit 7
> {code}
> This query  doesn't end. I found attached error message in tajo worker's log.
