[jira] [Created] (HIVE-30100) Post-run integrity checks for metatool column de-duplication

Zhihua Deng created HIVE-30100:
----------------------------------

             Summary: Post-run integrity checks for metatool column de-duplication
                 Key: HIVE-30100
                 URL: https://issues.apache.org/jira/browse/HIVE-30100
             Project: Hive
          Issue Type: Improvement
            Reporter: Zhihua Deng
            Assignee: Zhihua Deng


HIVE-29724 added -dedupColumns to reduce duplicate column descriptor (CD) metadata. The tool reports how many storage descriptors were updated and CDs removed, but it does not confirm afterward that the metastore still reflects the same partition/table column definitions. Without that step, operators must infer success from counts alone or run manual checks.

This improvement adds an automated post-run validation pass so teams can run the tool in production with clear pass/fail confidence.
