Hi Subru,
What's should I do if I wanna get a task
> Federation Global Policy Generator (load balancing)
> ---------------------------------------------------
>
> Key: YARN-3660
> URL: https://issues.apache.org/jira/browse/YARN-3660
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Carlo Curino
> Assignee: Subru Krishnan
> Priority: Major
>
> In a federated environment, local impairments of one sub-cluster might
> unfairly affect users/queues that are mapped to that sub-cluster. A
> centralized component (GPG) runs out-of-band and edits the policies governing
> how users/queues are allocated to sub-clusters. This allows us to enforce
> global invariants (by dynamically updating locally-enforced invariants).
