Carlo Curino commented on YARN-1707: ------------------------------------ This patch is a more "minimal" set of changes rebased on trunk after we committed to trunk YARN-2378, YARN-2389. We also simplified and added more tests. The dynamic behavior is for PlanQueue and ReservationQueue. > Making the CapacityScheduler more dynamic > ----------------------------------------- > > Key: YARN-1707 > URL: https://issues.apache.org/jira/browse/YARN-1707 > Project: Hadoop YARN > Issue Type: Sub-task > Components: capacityscheduler > Reporter: Carlo Curino > Assignee: Carlo Curino > Labels: capacity-scheduler > Attachments: YARN-1707.2.patch, YARN-1707.patch > > > 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)
