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.
