Anubhav Dhoot created YARN-2773:
-----------------------------------
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
