[jira] [Created] (FLINK-1496) Events at unitialized input channels are lost

Ufuk Celebi created FLINK-1496:
----------------------------------

             Summary: Events at unitialized input channels are lost
                 Key: FLINK-1496
                 URL: https://issues.apache.org/jira/browse/FLINK-1496
             Project: Flink
          Issue Type: Bug
          Components: Distributed Runtime
    Affects Versions: master
            Reporter: Ufuk Celebi


If a program sends an event backwards to the producer task, it might happen that some of it input channels have not been initialized yet (UnknownInputChannel). In that case, the events are lost and will never be received at the producer.
