> 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.
