> 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)
