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

Sorry [~yanghua], I actually have a fix ready but did not see that you assigned the issue to yourself. If it's ok, then I would take this issue.

>             Project: Flink
>          Issue Type: Bug
>          Components: Distributed Coordination
>    Affects Versions: 1.5.0, 1.6.0

>            Assignee: vinoyang
>            Priority: Critical
>
> Currently, the {{Dispatcher}} does not clean up the {{RunningJobsRegistry}} after the job has finished. The consequence is that a ZNode with the JobID and a state num per job remains in ZooKeeper.
> We should clean up these ZNodes to avoid a resource leak.
