> YARN Federation today requires manual configuration of queues within each sub-cluster, and each RM operates "in isolation". This has few issues:
> # Preemption is computed locally (and might far exceed the global need)
> # Jobs within a queue are forced to consume their resources "evenly" based on queue mapping
> This umbrella JIRA tracks a new feature that leverages the FederationStateStore as a synchronization mechanism among RMs, and allows for allocation and preemption decisions to be based on a (close to up-to-date) global view of the cluster allocation and demand.
