Zili Chen commented on FLINK-15086:
-----------------------------------
Since currently the choice detach or attach can be done by user itself, my
opinion is that we doesn't close JobCluster in {{MiniDispatcher}} in attach
mode, but let the client send a shutdown request on close.
> JobCluster may not be shutdown if executeAsync called

> Project: Flink
> Issue Type: Bug
> Components: Client / Job Submission, Runtime / Coordination
> Reporter: Zili Chen
> Priority: Major
>
> If a JobCluster started in attached execution mode, it will wait for a client
> requesting its result and shutdown itself. However, there is no permission
> that a user get {{JobClient}} from {{executeAsync}} call
> {{getJobExecutionResult}} so the cluster may remain.
