Carlo Curino commented on YARN-1707: ------------------------------------ Agreed on all of the above. {quote} I think for moving application across queue is not a ReservationSystem specific change. I would suggest to check it will not violate restrictions in target queue before moving it. {quote} This makes sense, we should compile a list of invariant to check for (I have a few in mind, but feedback is likely useful). Thanks, Carlo > 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.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)
