The consensus is that for the first iteration we will have a single boolean flag per leaf queue to specify whether the queue is reservable or not. This is mutually exclusive to the _parent_ flag, i.e. either a leaf queue can be a dynamic parent queue or it can be reservable. We will have defaults for _ReservationAgent_, _Replanner_ etc which will be overrideable at scheduler level. I agree with [~kasha] that we should hide the dynamic reservation queues from the user. Can we use _ReservationSchedulerConfiguration::getShowReservationAsQueues_ to show/hide the dynamic reservation queues in web UI? Also we need the equivalent of _CapacityScheduler::resolveReservationQueueName_ for the _AppAddedSchedulerEvent_ in FS and _handleMoveToPlanQueue_ for _moveApplication_ ) > Add FairReservationSystem for FairScheduler > ------------------------------------------- > > Key: YARN-2738 > URL: https://issues.apache.org/jira/browse/YARN-2738 > Project: Hadoop YARN > Issue Type: Sub-task > Components: fairscheduler > Reporter: Anubhav Dhoot > Assignee: Anubhav Dhoot > Attachments: YARN-2738.001.patch, YARN-2738.002.patch, YARN-2738.003.patch > > > Need to create a FairReservationSystem that will implement ReservationSystem for FairScheduler -- This message was sent by Atlassian JIRA (v6.3.4#6332)
