Sergey Shelukhin commented on HIVE-18457:
-----------------------------------------
Updated the output.
I'm not sure why it doesn't look like the flag is updated... seems to work fine
in derby. Are there any errors from alter? we might need to investigate why DN
won't update the table if this reproes.
> improve show plan output (triggers, mappings)
