Anubhav Dhoot commented on YARN-2773:
-------------------------------------
getAdmissionPolicy uses the planQueuePath (fully qualified) while rest of the
methods (e.g. getPlanQueueCapacity) uses planQueueName (just leaf queue name).
> ReservationSystem's use of Queue names vs paths is inconsistent for
> CapacityReservationSystem and FairReservationSystem

> Key: YARN-2773
> URL: https://issues.apache.org/jira/browse/YARN-2773
> Project: Hadoop YARN
> Issue Type: Bug
> Components: scheduler
> Reporter: Anubhav Dhoot
> Priority: Minor
>
> Reservation system requires use the ReservationDefinition to use a queue name
> to choose which reservation queue is being used. CapacityScheduler does not
> allow duplicate leaf queue names. Because of this we can refer to a unique
> leaf queue by simply using its name and not full path (which includes
> parentName + "."). FairScheduler allows duplicate leaf queue names because of
> which one needs to refer to the full queue name to identify a queue uniquely.
> This is inconsistent for the implementation of the AbstractReservationSystem
> where one implementation of getQueuePath will do conversion
> (CapacityReservationSystem) while the FairReservationSystem will return the
> same value back
