Status: Patch Available (was: Open)
> Allow UDFs/UDTFs to indicate whether they can run with fetch task conversion
> ----------------------------------------------------------------------------
>
> Key: HIVE-13586
> URL: https://issues.apache.org/jira/browse/HIVE-13586
> Project: Hive
> Issue Type: Improvement
> Components: UDF
> Reporter: Jason Dere
> Assignee: Jason Dere
> Attachments: HIVE-13586.1.patch
>
>
> Some UDFs/UDTFs cannot run properly with fetch task conversion.
> For UDFs:
> - The UDF may be depending on files/archives added to the distributed cache,
> which may not be available in the local fetch task.
> - The UDF may be depending on GenericUDF.configure() to be called - this is
> not called for locally run UDFs.
> For UDTFs, one issue is HIVE-11892.
> A bit of a workaround, but for such UDFs/UDTFs we can have a flag to indicate
> whether the UDF should be allowed to run in a local fetch task.
