    // add additional resource with the new value
    // so the server side will pick it up
    String rsrc = "testRefreshSuperUserGroupsConfiguration_rsrc.xml";
    addNewConfigResource(rsrc, userKeyGroups, "gr2", userKeyHosts, "127.0.0.1");  
    
    MRAdmin admin = new MRAdmin(config);
    String [] args = new String[]{"-refreshSuperUserGroupsConfiguration"};
    admin.run(args);
    
    try {
      ProxyUsers.authorize(ugi2, "127.0.0.1", config);
