--------------------------------------

             Summary: Shut down "Storm Topologies" clenaly
                 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:

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).
