Sergey Shelukhin commented on HIVE-19055:
-----------------------------------------
Actually, one use case (replace active plan) does rely semantically on the null
plan. Looks like local metastore doesn't go thru thrift validation so it works
in tests.
The better approach is to make the value nullable.
> WM alter may fail if the name is not changed
