> Currently getPendingResourceRequestForAttempt is present in 
> {{AbstractYarnScheduler}}.
> *But in AppInfo,  we are calling this method by typecasting it to 
> AbstractYarnScheduler, which is incorrect.*
> Because if a custom scheduler is to be added, it will implement 
> YarnScheduler, not AbstractYarnScheduler.
> This method should be moved to YarnScheduler or it should have a guarded 
> check like in other places (RMAppAttemptBlock.getBlackListedNodes)
