-----------------------------------
Summary: Shut down "Storm Topologies" cleanly (was: Shut down "Storm
Topologies" clenaly)
> Shut down "Storm Topologies" cleanly
> ------------------------------------
>
> Key: FLINK-2338
> URL: https://issues.apache.org/jira/browse/FLINK-2338
> Project: Flink
> Issue Type: Improvement
> Components: flink-contrib
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Minor
>
> Currently, it is not possible to stop a Flink streaming program in a clean
> way. Thus, emulating Storm's "kill" command is done the "hard way" resulting
> in the following exception shown in the log:
> org.apache.flink.runtime.client.JobExecutionException: Communication with
> JobManager failed: Lost connection to JobManager akka://flink/user/jobmanager
> at
> org.apache.flink.runtime.client.JobClient.submitJobAndWait(JobClient.java:169)

> The exception is expected currently. However, a clean "kill" is preferable.
> This can done after the new STOP signal is available
> (https://issues.apache.org/jira/browse/FLINK-2111).
