## *Tips* - *Thanks very much for contributing to Apache DolphinScheduler.* - *Please review https://dolphinscheduler.apache.org/en-us/community/index.html before opening a pull request.* ## What is the purpose of the pull request Improvement #3690 The current policy is to take the first one, but the first test is not fixed。This is my debug screenshot. 当前策略是取第一个,但是第一个测试下来也是不固定的,这个是我调试截图。 ![image](https://user-images.githubusercontent.com/59079269/92440617-5daf6c00-f1df-11ea-8e45-ea2fd2be25a9.png) ![image](https://user-images.githubusercontent.com/59079269/92440630-61db8980-f1df-11ea-8acf-dc2341baee0d.png) The problem is that on the server, the acquired IP is the external network card IP.External network control is more strict, so it is not a full port through. Therefore, it is recommended to get IP of Intranet card first.So make logical optimizations in your code. 遇到的问题是服务器上,获取的ip为外网网卡ip.外网控制比较严格,所以不是全端口打通。所以,建议优先获取内网网卡ip。 所以做出代码中的逻辑优化。 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
