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

             Summary: Pluggable sharing policy for Partition Node Label resources
                 Key: YARN-4425
                 URL: https://issues.apache.org/jira/browse/YARN-4425
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: capacity scheduler, resourcemanager
            Reporter: Naganarasimha G R
            Assignee: Naganarasimha G R


As part of support for sharing NonExclusive Node Label partitions in YARN-3214, NonExclusive
partitions are shared only to Default Partitions and also have fixed rule when apps in default
partitions makes use of resources of any NonExclusive partitions.

There are many scenarios where in we require pluggable policy like MutliTenant, Hierarchical
etc.. where in each partition can determine when they want to share the resources to other
paritions and when other partitions wants to use resources from others
More details in the attached document.
