[jira] [Created] (HIVE-16189) Table column stats might be invalidated in a failed table rename

Chaoyu Tang created HIVE-16189:
----------------------------------

             Summary: Table column stats might be invalidated in a failed table rename
                 Key: HIVE-16189
                 URL: https://issues.apache.org/jira/browse/HIVE-16189
             Project: Hive
          Issue Type: Bug
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang


If the table rename does not succeed due to its failure in moving the data to the new renamed table folder, the changes in TAB_COL_STATS are not rolled back which leads to invalid column stats.
