Ashutosh Chauhan commented on HIVE-21254:
-----------------------------------------
It should be determined whether table is acid or not. Pre-upgrade tool need to
compact acid tables. Thats a must, we can't skip it. If it's a non-acid table
then no action is needed on it anyways, so ACE exception can be ignored, but if
its an acid table then I think tool shall raise an exception and fail. User
need to make sure that user running pre-upgrade tool has sufficient privileges.
> Pre-upgrade tool should handle exceptions and skip db/tables

> When exceptions like AccessControlException is thrown, pre-upgrade tool
> fails. If hive user does not have read access to database or tables (some
> external tables denies read access to hive), pre-upgrade tool should just
> assume they are external tables and move on without failing pre-upgrade
> process.
