-----------------------------------
Resolution: Fixed
Fix Version/s: 0.1.0-incubating
> Flink Create Functions call Collector.close()
> ---------------------------------------------

> Key: BEAM-295

> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Fix For: 0.1.0-incubating
>
>
> {{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.
