>
> Key: YARN-7402
> URL: https://issues.apache.org/jira/browse/YARN-7402
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: federation
> Reporter: Carlo Curino
> Assignee: Carlo Curino
>
> 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.
