> 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 :
> {noformat}
> 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)
> {noformat}
> 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.
