> FairScheduler HeadRoom calculation should exclude nodes in the blacklist.
> MRAppMaster does not preempt the reducers because for Reducer preemption
> calculation, headRoom is considering blacklisted nodes. This makes jobs to
> hang forever(ResourceManager does not assign any new containers on
> blacklisted nodes but availableResource AM get from RM includes blacklisted
> nodes available resource).
> This issue is similar as YARN-1680 which is for Capacity Scheduler.
