> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerEventLog.shutdown() might ignore java.lang.Exception
> Inconsistent synchronization of org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairSchedulerEventLog.logDisabled; locked 50% of time
> Inconsistent synchronization of org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.QueueManager.queueMaxAppsDefault; locked 50% of time
