[jira] [Created] (IMPALA-11718) Improve support for Hive Generic UDFs

Csaba Ringhofer created IMPALA-11718:
----------------------------------------

             Summary: Improve support for Hive Generic UDFs
                 Key: IMPALA-11718
                 URL: https://issues.apache.org/jira/browse/IMPALA-11718
             Project: IMPALA
          Issue Type: New Feature
          Components: Catalog, Frontend
            Reporter: Csaba Ringhofer


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.
