   Yes, but if we deploy the application on yarn cluster  in product, it's not reasonable to config the jmx port for each application, and the jmx port may be be conflicts. 
   
   what about the bellow program, we can control the jmx port in our program, and update metrics by `ManagementFactory.getPlatformMBeanServer();`
   
   ```
   public void start(int port) throws Exception {
   
       LocateRegistry.createRegistry(port);
   
       String serviceUrl = "service:jmx:rmi://localhost:" + port + "/jndi/rmi://localhost:" + port + "/jmxrmi";
       JMXServiceURL url = new JMXServiceURL(serviceUrl);
       JMXConnectorServer connector = JMXConnectorServerFactory.newJMXConnectorServer(url, null, ManagementFactory.getPlatformMBeanServer());
   
       connector.start();
   
   }
   ```
