> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime, JobManager, Local Runtime,
> Streaming, TaskManager, Webfrontend
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Minor
>
> Currently, streaming jobs can only be stopped using "cancel" command, what is
> a "hard" stop with no clean shutdown.
> The new introduced "stop" signal, will only affect streaming source tasks
> such that the sources can stop emitting data and shutdown cleanly, resulting
> in a clean shutdown of the whole streaming job.
> This feature is a pre-requirment for
