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.
> AM-Used Resource for leafqueue is wrongly populated if AM ResourceRequest is
> less than minimumAllocation

> Project: Hadoop YARN
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 2.6.0
> Reporter: Rohith

>
> 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.
