Subject [jira] [Created] (YARN-7402) Federation: Global Queues
Date Fri, 27 Oct 2017 00:07:00 GMT
Carlo Curino created YARN-7402:

             Summary: Federation: Global Queues
                 Key: YARN-7402
                 URL: https://issues.apache.org/jira/browse/YARN-7402
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: federation
            Reporter: 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.
