> 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.
