> In related to this: https://issues.apache.org/jira/browse/IMPALA-8551
> when granting/revoking to an invalid user/group, Ranger only throws a generic
> Exception which a generic error message, such as "HTTP: 400: foo is Not
> Found". This could happen when:
> - grantor is an invalid user
> - the target grant user is invalid
> - the target grant group is invalid.
> It would be nice if Ranger could either throw a specialized exception or
> update the error message to provide more information.
