    namesystem.writeLock();
    try {
        if (newVal == null) {
            // set to default
            datanodeManager.setHeartbeatInterval(DFS_HEARTBEAT_INTERVAL_DEFAULT);
            return String.valueOf(DFS_HEARTBEAT_INTERVAL_DEFAULT);
        } else {
            datanodeManager.setHeartbeatInterval(Long.parseLong(newVal));
