No heartbeat to Ambari from newly provisioned dataNode

[#1]

Hi - there is a newly added data node on my HDP 2.5 cluster, and this m/c is not sending heartbeat to Ambari

I did the following to try & fix, but that didn't work out.

- restarted ambari service

-validated /etc/hosts - it has the IP of the correct machine

Any ideas on how to fix the issue ?

Verify the following:

1. If there is an ambari-agent installed on newly provisioned datanode.

2. If there is an ambari-agent installed try to restart it

3. Verify the version of ambari-agent and ambari-server, they both must be SAME.

@Dinesh Chitlangia - thanks for the input.

yes, i noticed the ambari-agent is not installed on the newly provisioned datanode, will install that & restart.

Cool, I remember I had faced similar problems when I first tried to add a new node. I guess you are using a lower version of ambari/sandbox just like me. Higher versions automatically install ambari-agents when adding a new node into the cluster.
