Description
YarnAuthorizationProvider AccessRequest has null RemoteAddress in case of FairScheduler. FSQueue#hasAccess uses Server.getRemoteAddress() which will be null when the call is from RMWebServices and EventDispatcher. It works fine when called by IPC Server Handler.
FSQueue#hasAccess is called at three places where (2) and (3) returns null.
1. IPC Server -> RMAppManager#createAndPopulateNewRMApp -> FSQueue#hasAccess -> Server.getRemoteAddress returns correct Remote IP.
2. IPC Server -> RMAppManager#createAndPopulateNewRMApp -> AppAddedSchedulerEvent
EventDispatcher -> FairScheduler#addApplication -> FSQueue.hasAccess -> Server.getRemoteAddress returns null

3. RMWebServices -> QueueACLsManager#checkAccess -> FSQueue.hasAccess -> Server.getRemoteAddress returns null.

Have verified with CapacityScheduler and it works fine.
