                 URL: https://issues.apache.org/jira/browse/DRILL-6938
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.13.0
            Reporter: Dony Dong


Hi Team

After we disable hashjoin and hashagg to fix out of memory issue, we got the wrong result.

With these two parameters enabled, we will get 8 rows. After we disable them, it only return 3 rows. It seems some MEM_ID had exclude before group or some other step.

select b.MEM_ID,count(distinct b.DEP_NO)
from dfs.test.emp b
where b.DEP_NO<>'-'
and b.MEM_ID in ('68','412','852','117','657','816','135','751')

and b.HIRE_DATE>'2014-06-01'
group by b.MEM_ID
order by 1;
