> 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.javaļ¼
> {code:java}
> if (conf.getBoolean(
> RBFConfigKeys.DFS_ROUTER_HEARTBEAT_ENABLE,
> RBFConfigKeys.DFS_ROUTER_HEARTBEAT_ENABLE_DEFAULT)) {
> // Create status updater for each monitored Namenode
> this.namenodeHeartbeatServices = createNamenodeHeartbeatServices();
> for (NamenodeHeartbeatService hearbeatService :
> this.namenodeHeartbeatServices) {
> addService(hearbeatService);
> }
> if (this.namenodeHeartbeatServices.isEmpty()) {
> LOG.error("Heartbeat is enabled but there are no namenodes to
> monitor");
> }
> // Periodically update the router state
> this.routerHeartbeatService = new RouterHeartbeatService(this);
> addService(this.routerHeartbeatService);
> }
