Rajkumar Singh commented on HIVE-19747:
---------------------------------------
it seems that you are missing the object in the command on which you want to
grant privileges. the command should be like this
{code}
grant all on database `default` to user abc;
{code}
> "GRANT ALL TO USER" failed with NullPointerException
