I try to solve it with google I already check these setting.

1. /etc/cloudera-scm-agent/config.ini the port set 7182 and server_host set ryze-1.bigdata.com.

2. iptable altready shutdown with sudo service iptables stop

3. ryze-1.bigdata.com is reachable. and telnet ryze-1.bigdata.com 7183 can succeed.

OS: Centos7.4 Platform: AliCloud
