Subject [jira] [Created] (YARN-2773) ReservationSystem's use of Queue names vs paths is inconsistent for CapacityReservationSystem and FairReservationSystem

-----------------------------------

             Summary: 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
