[jira] [Commented] (FLINK-15086) JobCluster may not be shutdown if executeAsync called

["Zili Chen (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-15086?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16989297#comment-16989297 ] 

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.

> 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.
