    Description

      This was reported by YARN-4238 QA report. Refer to https://builds.apache.org/job/PreCommit-YARN-Build/10389/testReport/

      Error reported is as under :

      org.mockito.exceptions.verification.TooManyActualInvocations: 
      noOpSystemMetricPublisher.appCreated(
          <any>,
          <any>
      );
      Wanted 3 times:
      -> at org.apache.hadoop.yarn.server.resourcemanager.TestRMRestart.testRMRestartGetApplicationList(TestRMRestart.java:955)
      But was 6 times. Undesired invocation:
      -> at org.apache.hadoop.yarn.server.resourcemanager.ResourceManager.recover(ResourceManager.java:1274)
      
      	at org.apache.hadoop.yarn.server.resourcemanager.TestRMRestart.testRMRestartGetApplicationList(TestRMRestart.java:955)
      

      Failing because in RMAppImpl#recover, sendATSCreateEvent has been called twice.
      Has been introduced during rebase I guess.
      After removing the duplicate call, the test passes.

      There is a findbugs warning in resourcemanager in YARN-2928 branch as well. Fix it as part of this JIRA itself.
