[jira] [Commented] (YARN-3999) Add a timeout when drain the dispatcher

    [ https://issues.apache.org/jira/browse/YARN-3999?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14648484#comment-14648484 ] 

Jian He commented on YARN-3999:
-------------------------------

Uploaded a patch which adds the timeout on draining the dispatcher. The value is set to be half of the am-rm-expiry-time. 
Beyond that, I also changed the order of a couple of services which might take long time to flush the events on stop.

> If external systems like ATS, or ZK becomes very slow, draining all the events take a lot of time. If this time becomes larger than 10 mins, all applications will expire. We can add a timeout and stop the dispatcher even if not all events are drained.
