[jira] [Created] (BEAM-295) Flink Create Functions call Collector.close()

Aljoscha Krettek created BEAM-295:
-------------------------------------

             Summary: Flink Create Functions call Collector.close()
                 Key: BEAM-295
                 URL: https://issues.apache.org/jira/browse/BEAM-295
             Project: Beam
          Issue Type: Bug
          Components: runner-flink
            Reporter: Aljoscha Krettek
            Assignee: Aljoscha Krettek


{{Collector.close()}} should only be called internally, by Flink. Calling close() in the user function, as we do in {{FlinkCreateFunction}} and {{FlinkStreamingCreateFunction}} will lead to downstream operations being closed twice, which can lead to faulty behavior.
