Subject [jira] [Updated] (YARN-7402) Federation V2: Global Optimizations
Date Tue, 09 Jan 2018 23:37:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7402?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Carlo Curino updated YARN-7402:
-------------------------------
        Summary: Federation V2: Global Optimizations  (was: Federation: Global Queues)
    Description: 
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. The JIRA also tracks algorithms
to automatically generate policies for Router and AMRMProxy to shape the traffic to each sub-cluster,
and general "maintenance" of the FederationStateStore.
