Subject [jira] [Created] (HIVE-9690) Allow non-numeric arithmetic operations
Date Fri, 13 Feb 2015 21:43:12 GMT
Jason Dere created HIVE-9690:
--------------------------------

             Summary: Allow non-numeric arithmetic operations
                 Key: HIVE-9690
                 URL: https://issues.apache.org/jira/browse/HIVE-9690
             Project: Hive
          Issue Type: Bug
          Components: UDF
            Reporter: Jason Dere
            Assignee: Jason Dere


Some refactoring for HIVE-5021. The current arithmetic UDFs are specialized for numeric types,
and trying to change the logic in the existing UDFs looks a bit complicated. A less intrusive
fix would be to create the date-time/interval arithmetic UDFs as a separate UDF class, and
to make the plus/minus UDFs act as a wrapper which would invoke the numeric or interval arithmetic
UDF depending on the args.
