             Summary: Can't use group by column alias
                 Key: TAJO-228
                 URL: https://issues.apache.org/jira/browse/TAJO-228
             Project: Tajo
          Issue Type: Bug
            Reporter: kim hyoung jun

I ran the bellow query which uses column alias and group by.
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

This query  doesn't end. I found attached error message in tajo worker's log.
