Subject [jira] [Commented] (YARN-3535) ResourceRequest should be restored back to scheduler when RMContainer is killed at ALLOCATED
Date Thu, 16 Jul 2015 06:40:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14629296#comment-14629296

zhihai xu commented on YARN-3535:
---------------------------------

Sorry for coming late into this issue.
The latest Patch looks good to me except one nit:
Can we make {{ContainerRescheduledTransition}} child class of {{FinishedTransition}} similar
as {{KillTransition}}?
So we can call {{super.transition(container, event);}} instead of {{new FinishedTransition().transition(container,
event);}}.
I think this will make the code more readable and match other transition class implementation.
