Ted Yu commented on HBASE-9284:
-------------------------------
The intention of the ProtobufUtil.getUserPermissions() call mentioned above is
to obtain permissions for Namespace specified by table_name argument.
A new method can be added to ProtobufUtil for such query.
> user_permission.rb uses wrong argument types for
> ProtobufUtil#getUserPermissions() call
