[jira] [Created] (HIVE-18618) Table stats on Micro-managed table becomes incorrect after INSERT OVERWRITE

Steve Yeom created HIVE-18618:
---------------------------------

             Summary: Table stats on Micro-managed table becomes incorrect after INSERT OVERWRITE
                 Key: HIVE-18618
                 URL: https://issues.apache.org/jira/browse/HIVE-18618
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 3.0.0
            Reporter: Steve Yeom
            Assignee: Steve Yeom


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.
