> UpdateTask message contains unused information
> ----------------------------------------------
>
> Key: FLINK-1810
> URL: https://issues.apache.org/jira/browse/FLINK-1810
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Affects Versions: 0.10.0
> Reporter: Ufuk Celebi
> Priority: Minor
>
> When deploying tasks to a task manager it not guaranteed that all results are
> already consumable. In such cases, the InputGate of the receiver creates
> "UnknownInputChannel" instances, which are updated during runtime to Local-
> or RemoteInputChannel instances.
> The UpdateTask Akka message which triggers this update contains unused
> information (the producing task's execution attempt ID) to identify which
> channel to update. I found this confusing when looking over the code and
> actually thought that it was a bug (because the unused information was
> actually erroneous).
