>    Affects Versions: 3.0.0

> Micromanage table INSERT OVERWRITE now does not clean existing delta directories
> during the operation. Instead compaction cleaner deletes obsolete directories.
> The current system does not compute correctly when it calculates table statistics
> since it does not ignore obsolete delta directories.
> A fix is already available in the patch of HIVE-18052. It would be valuable to separate
> the code changes into this jira ticket.
