Nico Kruber updated FLINK-9755:
-------------------------------
Priority: Critical (was: Major)
> Exceptions in RemoteInputChannel#notifyBufferAvailable() are not propagated
> to the responsible thread
> -----------------------------------------------------------------------------------------------------
>
> Key: FLINK-9755
> URL: https://issues.apache.org/jira/browse/FLINK-9755
> Project: Flink
> Issue Type: Bug
> Components: Network
> Affects Versions: 1.5.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
> Priority: Critical
> Fix For: 1.6.0, 1.5.2
>
>
> The credit-based flow control implementation of
> RemoteInputChannel#notifyBufferAvailable() does not forward errors (like the
> {{IllegalStateException}}) to the thread that is being notified. The calling
> code at {{LocalBufferPool#recycle}}, however, relies on the callback
> forwarding errors and completely ignores any failures.
> Therefore, we could end up with a program waiting forever for the callback
> and not even a failure message in the logs.
