> FSAppAttempt adds duplicate ResourceRequest to demand in updateDemand. We should only count ResourceRequest for ResourceRequest.ANY when calculate demand.
> Because {{hasContainerForNode}} will return false if no container request for ResourceRequest.ANY and both {{allocateNodeLocal}} and {{allocateRackLocal}} will also decrease the number of containers for ResourceRequest.ANY.
> This issue may cause current memory demand overflow(integer) because duplicate requests can be on multiple nodes.
