> {{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}}.
