nboding opened a new issue #2409: [BUG] zk中masters注册ip127.0.0.1 URL: https://github.com/apache/incubator-dolphinscheduler/issues/2409 *For better global communication, please give priority to using English description, thx! * **Describe the bug** bug : zookeeper masters znode list ip address is 127.0.0.1，instead of wanted ip eth0 or eth1 chinese describe：zk中注册的master信息ip地址是127.0.0.1，而不是配置的域名所对应或者解析的ip地址。官网文档中建议在/etc/hosts中注释掉127.0.0.1这条解析，我觉得不合适。 **To Reproduce** Steps to reproduce the behavior, for example: 1、zookeeper znode info： [zk: localhost:2181(CONNECTED) 6] ls /dolphinscheduler/masters [127.0.0.1] 2、ds install_config info： installPath=/usr/local/dolphinscheduler deployUser=dolphinscheduler ips=ds1 sshPort=60022 masters=ds1 workers=ds1 alertServer=ds1 apiServers=ds1 3、/etc/hosts info $cat /etc/hosts 127.0.0.1 localhost hadoop1 10.3.57.15 ds1 hadoop1 **Expected behavior** A clear and concise description of what you expected to happen. **Screenshots** If applicable, add screenshots to help explain your problem. **Which version of Dolphin Scheduler:** 1.2.1 **Additional context** **Requirement or improvement - Please describe about your requirements or improvement suggestions. bug fix try: 1、confirm hostname $hostname hadoop1 2、hostname -i 127.0.0.1 10.3.57.15 3、edit /etc/hosts,delete hadoop1 from 127.0.0.1 record $cat /etc/hosts 127.0.0.1 localhost 10.3.57.15 ds1 hadoop1 4、hostname -i 10.3.57.15 it is ok chinese describe: hostname命令返回的服务器主机名，hostname -i 返回的是服务器主机名在/etc/hosts中所有匹配的ip地址 所以我把/etc/hosts中127.0.01中的主机名删掉，只保留内网ip的解析就可以了，没必要把127.0.0.1整条注释掉, 只要hostname命令返回值 在/etc/hosts中对应的内网ip正确就可以，ds程序肯定是取了第一个值，我理解上ds程序不应该用hostname -i 取值这样有点问题，因为好多公司服务器的主机名都是运维配置的，感觉还是直接取配置文件的域名解析的返回ip更准确，或者znode中存域名信息而不是ip addr。
