> 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.
