          Issue Type: Bug
          Components: capacity scheduler
    Affects Versions: 3.1.0
            Reporter: yimeng


I tested ReservationSystem in Hadooop 3.0,but it seems have problem.

1.config yarn.resourcemanager.reservation-system.enable = true in RM yarn-site.xml 

2.select a leaf queue "bbb" ,config yarn.scheduler.capacity.root.bbb.reservable = true  in capacity-scheduler.xml,as follow

<property>

<name>yarn.scheduler.capacity.root.bbb.reservable</name>
<value>true</value>
</property>

3.then restart RM ,the RM start failed .The error stack log is as follows:

I am sure the queue "bbb" is a leaf queue.
