Subject [jira] [Commented] (YARN-3305) AM-Used Resource for leafqueue is wrongly populated if AM ResourceRequest is less than minimumAllocation
Date Thu, 12 Mar 2015 19:05:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-3305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14359186#comment-14359186

Jian He commented on YARN-3305:
-------------------------------

[~rohithsharma], thanks for working on this ! 
I think we can call normalize the am request in RMAppManager after validateAndCreateResourceRequest
to make sure the am request stored in RMAppIml is also correct.

> For given any ResourceRequest, {{CS#allocate}} normalizes request to minimumAllocation
if requested memory is less than minimumAllocation.
> But AM-used resource is updated with actual ResourceRequest made by user. This results
in AM container allocation more than Max ApplicationMaster Resource.
> This is because AM-Used is updated with actual ResourceRequest made by user while activating
the applications. But during allocation of container, ResourceRequest is normalized to minimumAllocation.
