-------------------------------------
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.
