> In fair scheduler, FSParentQueue and FSLeafQueue do an 
> assignContainerPreCheck to guaranty this queue is not over its limit.
> But the fitsIn function in Resource.java did not return false when the 
> usedResource equals the maxResource.
> I think we should create a new Function "fitsInWithoutEqual" instead of 
> "fitsIn" in this case.
