Description

The usage message from code does not match with the one documented.
1. "java ResourceManager " should be "yarn resourcemanager "

 private static void printUsage(PrintStream out) {
    out.println("Usage: java ResourceManager [-format-state-store]");
    out.println("                            "
        + "[-remove-application-from-state-store <appId>]" + "\n");
  }
