Description

The query is like following :

insert overwrite into lineitem_tmp
select
  l_partkey as t_partkey, 0.2 * avg(l_quantity) as t_avg_quantity
from
  lineitem
group by l_partkey;

It is from query #17 of TPC-H.

From eb2, only 2 tasks were not running after TA_ASSIGNED and query was in infinite loop.
It ran on TPC-H 10TB.
