> The compiler expects principals (user, group and role) as hive identifiers
> for authorization DDLs. The user and group are entities that belong to
> external namespace and we can't expect those to follow hive identifier syntax
> rules. For example, a userid or group can contain '-' which is not allowed by
> compiler.
