> 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.
