Summary: 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
Reporter: Carlo Curino
Assignee: Subru Krishnan
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).
