> findbugs warning:Inconsistent synchronization of
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.allocConf
> The findbugs warning found out two Unsynchronized access:
> 1. FairScheduler.getPlanQueues.
> It looks like we should add lock at FairScheduler.getPlanQueues.
> Because getPlanQueues will be called by
> AbstractReservationSystem.reinitialize.
> 2. FairScheduler.getAllocationConfiguration, which looks like ok without lock.
