Description

dfs.federation.router.namenode.heartbeat.enable is suppose to take the value of dfs.federation.router.heartbeat.enable when it isn't explicitly specified. by ::

    boolean isRouterHeartbeatEnabled = conf.getBoolean(
        RBFConfigKeys.DFS_ROUTER_HEARTBEAT_ENABLE,
        RBFConfigKeys.DFS_ROUTER_HEARTBEAT_ENABLE_DEFAULT);
    boolean isNamenodeHeartbeatEnable = conf.getBoolean(
        RBFConfigKeys.DFS_ROUTER_NAMENODE_HEARTBEAT_ENABLE,
        isRouterHeartbeatEnabled);

But since now RBF-Defaults are added by default, this logic doesn't hold, and the value defaults to true.
