Subramaniam Krishnan updated YARN-1707: --------------------------------------- Attachment: YARN-1707.9.patch Uploading a new patch with a minor change. Renamed ReservationQueue#changeCapacity to ReservationQueue#setEntitlement for consistency. > 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-1707.3.patch, YARN-1707.4.patch, > YARN-1707.5.patch, YARN-1707.6.patch, YARN-1707.7.patch, YARN-1707.8.patch, > YARN-1707.9.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 (v6.3.4#6332)
