> 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.
