> 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.
