Subject [jira] [Created] (BEAM-333) Support "stop" for streaming pipelines
Date Fri, 10 Jun 2016 06:33:21 GMT
Emanuele Cesena created BEAM-333:
------------------------------------

             Summary: Support "stop" for streaming pipelines
                 Key: BEAM-333
                 URL: https://issues.apache.org/jira/browse/BEAM-333
             Project: Beam
          Issue Type: Bug
          Components: runner-flink
            Reporter: Emanuele Cesena


Run:
```
$ flink run -c org.apache.beam.runners.flink.examples.streaming.KafkaWindowedWordCountExample
/path/to/fat.jar
```

The job properly runs. Trying to stop it fails. (Cancelling works fine.)

```
$ flink list
