How can I start my Ambari heartbeat?I'm a beginner in hortonworks. After installation and changing the ip address, I have got ambari all services down and All Heartbeat Lost! How can I overcome this situation? Thank you in advance.
@Hadi Bitalebi when you change IP address what do you mean? On Ambari server or agent? You need to make sure they both know each others address. Look in /etc/ambari-agent/conf/ambari-agentr.ini the server address. Check /etc/hosts on both servers and fix up. Fix ssh or manual registration on both.
This can be little tricky and that's why you must use hostname or FQDN for the ambari install. Did you install the cluster using IP address ?
Or It's sandbox environment.
My suggestion is to reinstall using Hostname....
if you cannot then you have to be creative ...See this http://www.swiss-scalability.com/2015/01/rename-host-in-ambari-170.html
Thank you for your suggestions, but this is a sandbox and it was all installed and I don't know how to change the host name to FQDN?! How can I reinstall Ambari in Sandbox?
