> Introduce a Cluster Monitor that aggregates load information from individual Node Managers and computes an ordered list of preferred Node managers to be used as target Nodes for OPPORTUNISTIC container allocations.
> This list can be pushed out to the Node Manager (specifically the AMRMProxy running on the Node) via the Allocate Response. This will be used to make local Scheduling decisions
