      Work Description: kgyrtkirk commented on pull request #2536:
URL: https://github.com/apache/hive/pull/2536#issuecomment-888100644


   `df3fc9b` had a clean testrun;
   the diff agains `df3fc9b` is only a [message change](https://github.com/kgyrtkirk/hive/compare/df3fc9b...388e350)
- which is clearly unrelated; will launch a flaky check.
