             Summary: 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: Bug
          Components: UDF
            Reporter: Jason Dere
            Assignee: Jason Dere


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.
