> 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.
