Heartbeat lost on AMBARI-SERVER 2.5

[#1]

I just upgrade Ambari from 2.2.0.0 to 2.5 and I noticed that HearBeat on Amari-server is lost. I also tried running ambari-agent on Ambari-server but still it's not coming back.

Can you check that the Ambari-agent is running on your Ambari host?

Did you also upgrade the Ambari agents? The ambari-agents versions should match the ambari-server version 🙂

Run this command on all the nodes and make sure their output match !

# yum list installed | grep ambari 

Once you have the same versions then restart all the ambari-agent

# ambari-agent restart 

Hope this resolves your lost heartbeat problem.

It's working on. I had to change the hostname from ambari-agent properties file. I restarted ambari-agent and it was OK after that. Thanks..
