Ashutosh Chauhan commented on HIVE-15045:
-----------------------------------------
Oracle which uses slightly different syntax allows both variants:
{code}
select empno, deptno, count(distinct empno) from scott.emp group by grouping
sets (empno, deptno);
select empno, deptno, count(distinct empno) from scott.emp group by cube
(empno, deptno);
{code}
> Count distinct throws error when used in conjunction with grouping set
