> Major compaction can be run when the execution engine is MR. This can cause data loss
a la HIVE-23703 (the fix for data loss when the execution engine is MR was reverted by HIVE-23763).
> Currently minor compaction can only be run when the execution engine is Tez, otherwise
it falls back to MR (non-query-based) compaction. We should extend this functionality to major
compaction as well.
