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

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).
