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.
