      Description

      We've seen some rare flakey failures in TestRMEmbeddedElector#testCallbackSynchronization:

      org.mockito.exceptions.verification.WantedButNotInvoked: 
      
      Wanted but not invoked:
      adminService.transitionToStandby(<any>);
      -> at org.apache.hadoop.yarn.server.resourcemanager.TestRMEmbeddedElector.testCallbackSynchronizationNeutral(TestRMEmbeddedElector.java:215)
      Actually, there were zero interactions with this mock.
