Description

Running TestJavaActionExecutor fails with fair scheduler

Failed tests: testSubmitWithLauncherQueue(org.apache.oozie.action.hadoop.TestJavaActionExecutor): 
 expected:<[]test> but was:<[root.]test>

Reason: FairScheduler adds a "root." prefix to the queue name in org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.QueueManager.ensureRootPrefix()

A potential way to fix the test case:

• we can add a new function

      private boolean isFairSchedulerUsed(Configuration conf) {
          return conf.get("yarn.resourcemanager.scheduler.class").contains(FairScheduler.class.getName());
      }
  

  that can be called from testSubmitWithLauncherQueue():

  ...
          if (isFairSchedulerUsed(conf)) {
              assertEquals("root.test", queue);
          }
          else {
              assertEquals("test", queue);
          }
  ...
