Subramaniam Venkatraman Krishnan reassigned YARN-2385: ------------------------------------------------------ Assignee: Subramaniam Venkatraman Krishnan (was: Karthik Kambatla) > Adding support for move all applications from a source queue to destination > queue > --------------------------------------------------------------------------------- > > Key: YARN-2385 > URL: https://issues.apache.org/jira/browse/YARN-2385 > Project: Hadoop YARN > Issue Type: Sub-task > Components: fairscheduler > Reporter: Subramaniam Venkatraman Krishnan > Assignee: Subramaniam Venkatraman Krishnan > Labels: fairscheduler > > The CapacityScheduler is a rather static at the moment, and refreshqueue > provides a rather heavy-handed way to reconfigure it. Moving towards > long-running services (tracked in YARN-896) and to enable more advanced > admission control and resource parcelling we need to make the > CapacityScheduler more dynamic. This is instrumental to the umbrella jira > YARN-1051. > Concretely this require the following changes: > * create queues dynamically > * destroy queues dynamically > * dynamically change queue parameters (e.g., capacity) > * modify refreshqueue validation to enforce sum(child.getCapacity())<= 100% > instead of ==100% > We limit this to LeafQueues. -- This message was sent by Atlassian JIRA (v6.2#6252)
