To my understanding, resource manager(RM) only knows the current active host by its "long" name; if a host is not seen, it will assume it is not active NOW. when RM sees a short name, it doesn't know this is a short name for some long name so it will not assign it to any node; but instead it will wait for some other hosts to register as the short name (which will not happen);
