Failed test is unrelated to this patch.

> 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.
