Subject [jira] [Commented] (YARN-1446) Change killing application to wait until state store is done
Date Tue, 03 Dec 2013 19:19:36 GMT

    [ https://issues.apache.org/jira/browse/YARN-1446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13838059#comment-13838059
] 

Zhijie Shen commented on YARN-1446:
-----------------------------------

bq. Investigate more, I think kill event can be ignored when App is at finishing state, because
attempt is anyways ignoring the kill event at Finishing. Here, we made a decision that an
application that has called unregistered even still remaining at Final_Saving state is not
killable, sounds reasonable ?

Make sense. Agree.

BTW, are the test failures related?

> When user kills an application, it should wait until the state store is done with saving
the killed status of the application. Otherwise, if RM crashes in the middle between user
killing the application and writing the status to the store, RM will relaunch this application
after it restarts.
