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

             Summary: Dispatcher does not start SubmittedJobGraphStore
                 Key: FLINK-8176
                 URL: https://issues.apache.org/jira/browse/FLINK-8176
             Project: Flink
          Issue Type: Bug
          Components: Distributed Coordination, Job-Submission
    Affects Versions: 1.5.0
            Reporter: Gary Yao
             Fix For: 1.5.0


{{Dispatcher}} never calls start on its {{SubmittedJobGraphStore}} instance. Hence, when a Job is submitted, an {{IllegalStateException}} is thrown:
{noformat}
java.lang.IllegalStateException: Not running. Forgot to call start()?

*Expected Behavior*
In {{start()}} method, the submittedJobGraphStore should be started as so:
{code}
submittedJobGraphStore.start(this);
{code}
To enable this, the {{Dispatcher}} must implement the interface {{SubmittedJobGraphStore.SubmittedJobGraphListener}}.
