-------------------------------

If I understood correctly, we could have certain policies to selected better candidate nodes
and seems its pluggable. cc/ [~leftnoteasy]

> In situation like YARN-6101, if we consider all type of resource(vcore, memory) utilization
on node rather than just answer we can allocate or not, we are more likely to have better
resource utilization as a whole.
> It is possible that we have a set of candidate nodes, then find the most promising node
to assign to one request considering node resource utilization with global scheduling.
