Ambari Heartbeat Lost during Installation

[#1]

We are trying to install , HDP via Ambari 2.1, but we during the install process, the ambari server (ambari-server.log) reports that it has lost an heart beat of the agent.

Error Message :

Heartbeat lost from host amabri.agent.com

The ambari-agent log reports:

Failed to connect to https://amabri-server.com:8440/connection_info due to [Errno 111] Connection refused

We are using openjdk 1.7 on RHEL 6.6 64 bit.

Any pointer to the issue would help immensely ?

what is the output of

curl –u user:passwd http://AmbariHost:8080/api/v1/hosts and curl –u user:passwd http://AmbariHost:8080/api/v1/clusters/YourClusterName/hosts.

Is the hosts listed are same?

is the machine with agent still up? Check the uptime. @Anilkumar Panda

@Anilkumar Panda

Make sure that your ambari host is correct

make sure that agent is up

iptables is off.
