Yufei Gu updated YARN-7311:
---------------------------
    Description: 
YARN-4248 introduced the REST API for submit/update/delete Reservations. Class 
{{TestRMWebServicesReservation}} intends to test both FS and CS. The test cases 
designed for fair scheduler test capacity scheduler instead. The following code 
in method {{configureServlets}} shows it set the scheduler to CS even test 
cases are for fair scheduler.
{code}
      conf.setClass(YarnConfiguration.RM_SCHEDULER, CapacityScheduler.class,
          ResourceScheduler.class);
      CapacitySchedulerConfiguration csconf =
          new CapacitySchedulerConfiguration(conf);
      String[] queues = { "default", "dedicated" };
      csconf.setQueues("root", queues);
      csconf.setCapacity("root.default", 50.0f);
      csconf.setCapacity("root.dedicated", 50.0f);
      csconf.setReservable("root.dedicated", true);
{code}
