John Sherman reassigned HIVE-24645:
-----------------------------------
> UDF configure not called when fetch task conversion occurs
> ----------------------------------------------------------
>
> Key: HIVE-24645
> URL: https://issues.apache.org/jira/browse/HIVE-24645
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Reporter: John Sherman
> Assignee: John Sherman
> Priority: Major
>
> When hive.fetch.task.conversion kicks in - UDF configure is not called.
> This is likely due to MapredContext not being available when this conversion
> occurs.
> The approach I suggest is to create a dummy MapredContext and provide it with
> the current configuration from ExprNodeGenericFuncEvaluator.
> It is slightly unfortunate that the UDF API relies on MapredContext since
> some aspects of the context do not apply to the variety of engines and
> invocation paths for UDFs which makes it difficult to make a fully formed
> dummy object such as the Reporter objects and the boolean around if it is a
> Map context.
