Work Description: deniskuzZ commented on pull request #2503:
URL: https://github.com/apache/hive/pull/2503#issuecomment-887407196
> Just checking – the goal of this change is to prevent concurrent
compaction and DDL operations?
>
> As discussed offline, verifyTableOrPartitionIdHasNotChanged might not be
needed because if the table (or partition) was dropped, then the compaction has
been removed from the queue and can't be marked failed, right? Or is it needed
after all?
it's started as HIVE-24235 , but once we introduced read locks that's no
longer needed. I'll remove it, however, that would require some tests changes
that mocked that method.
