-----------------------------
Status: Patch Available (was: Open)
> Move some string UDFs to GenericUDFs, for better varchar support
> ----------------------------------------------------------------
>
> Key: HIVE-5278
> URL: https://issues.apache.org/jira/browse/HIVE-5278
> Project: Hive
> Issue Type: Improvement
> Components: Types, UDF
> Reporter: Jason Dere
> Assignee: Jason Dere
> Attachments: HIVE-5278.1.patch
>
>
> To better support varchar/char types in string UDFs, select UDFs should be
> converted to GenericUDFs. This allows the UDF to return the resulting
> char/varchar length in the type metadata.
> This work is being split off as a separate task from HIVE-4844. The initial
> UDFs as part of this work are concat/lower/upper.
> NO PRECOMMIT TESTS - dependent on HIVE-4844
