I was going through below mentioned link if i need to setup CA signed certificate. I am going to mention list of steps to be performed on 3 node cluster(excluding edge node). Please validate
Kindly let me know if this is correct approach? Or is there any other link for multi node?
Thanks for great help!!
Check below things -
1. /etc/ambari-agent/conf/ambari-agent.ini has entry pointing to ambari server -> server=<ambari_host>
2. Check if iptables and selinux are stopped and disabled.
3. Try restarting the agent $ambari-agent restart
4. Check if there is issue with /etc/hosts file. Wrong/incorrect intry in /etc/hosts file can create such issue.
Thanks for replying. I have checked the ambari-agent.ini file at all hosts and it is same and ambari-server IP is also correct. All my services were running before setting up SSL. I stopped HDFS, Yarm, Mapreduce and made ssl related changes as mentioned up, since then i am unable to bring up the services due to error mentioned in question.
