Hi @kgyrtkirk, what do you think about this? there are also some tests like [groupby11.q](https://github.com/apache/hive/blob/7b3ecf617a6d46f48a3b6f77e0339fd4ad95a420/ql/src/test/queries/clientpositive/groupby11.q) and [groupby8_map_skew.q](https://github.com/apache/hive/blob/7b3ecf617a6d46f48a3b6f77e0339fd4ad95a420/ql/src/test/queries/clientpositive/groupby8_map_skew.q) showing the changes in partition columns after applying the fix.
