> The good feature of FairScheduler is added recently to YARN. As recently PreCommit test from MAPREDUCE-4309, there are several bugs found by Findbugs related to FairScheduler:
> 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
