> minResources and maxResources in fair scheduler configs are expressed in terms of absolute
numbers X mb, Y vcores. 
> As a result, when we expand or shrink our hadoop cluster, we need to recalculate and
change minResources/maxResources accordingly, which is pretty inconvenient.
> We can circumvent this problem if we can optionally configure these properties in terms
of percentage of cluster capacity.
