While Working on HIVE-11110, I ran into the following wrong results:
https://github.com/apache/hive/blob/master/ql/src/test/results/clientpositive/spark/groupby_cube1.q.out#L478
This happens in spark mode. The following is the diff.

The purpose of this jira is to see why the above query is failing.
