             Summary: Create ClusterManager to compute ordered list of preferred NMs for QUEUEABLE
containers
                 Key: YARN-4412
                 URL: https://issues.apache.org/jira/browse/YARN-4412
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Arun Suresh
            Assignee: Arun Suresh


Introduce a Cluster Manager that aggregates Load and Policy information from individual Node
Managers and computes an ordered list of preferred Node managers to be used as target Nodes
for QUEUEABLE 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
