> IMPALA-11162 has provided support for loading and running HIve generic UDFs, but it does not support handling them in an actually generic way, so the all overloads has to be added separately with argument and return types, similarly to non-persistent legacy Hive UDFs. This also means that the generic UDFs cannot be persisted to HMS, which doesn't expect argument/return type, only a .jar path and a function name.
> This ticket is  created to add support for actual generic handling and persistence to HMS.
