> Now, if i enable the heartbeat.enable, but i do not want to monitor any 
> namenode, i get an ERROR log like:
> {code:java}
> [2018-04-19T14:00:03.057+08:00] [ERROR] 
> federation.router.Router.serviceInit(Router.java 214) [main] : Heartbeat is 
> enabled but there are no namenodes to monitor
> {code}
> and if i disable the heartbeat.enable, we cannot get any mounttable update, 
> because the following logic in Router.javaļ¼š
> {code:java}
> if (conf.getBoolean(
>         RBFConfigKeys.DFS_ROUTER_HEARTBEAT_ENABLE,
>         RBFConfigKeys.DFS_ROUTER_HEARTBEAT_ENABLE_DEFAULT)) {
