-----------------------------------
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.
{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.
