> Currently, the RM has no way of returning requests that cannot be met. e.g. if the app wants a specific node and that node dies, then the RM should return that request instead of holding onto to it indefinitely. Currently, since every request can be met at * locality such a situation is hard to repro. It can however happen that all nodes in a cluster become unavailable. At that point, there is no way the RM can inform the apps about its inability to allocate requests.
