> 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)
