> When cancelling a pending slot allocation request on the {{ResourceManager}}, then we should also check whether we still need all the requested containers. If it turns out that we no longer need them, then we should try to cancel the unnecessary container requests. That way Flink will be, for example, a better Yarn citizen which quickly releases resources and resource requests if no longer needed.
