Subject [jira] [Commented] (YARN-1644) RM-NM protocol changes and NodeStatusUpdater implementation to support container resizing
Date Thu, 23 Jul 2015 23:18:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-1644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14639660#comment-14639660
] 

Jian He commented on YARN-1644:
-------------------------------

thanks [~mding]! one moment on the patch:

- NodeStatusUpdaterImpl#getIncreasedContainers and the change in ContainerManagerImpl:
If RM restarts right after NM sends the increased containers, NM may not yet update the container
status and still sends the old resource and therefore RM will recover the container with old
resource. How about we re-use the same containerStatus object for the increasedContainer ?
this way we can also avoid this situation.
