Please check if you have the following file present ?

/usr/lib/python2.6/site-packages/ambari_agent/AmbariConfig.py

.

Also if you have performed any ambari agent/server upgrade then chances are very high that these files might not be upgraded properly. If you still find any issue then try reinstalling ambari agent.

Solved after reinstalling ambari agent. Thanks !

Can you try to reinstall it on the node that's causing a problem,you will first need to stop the agent, then run the below commands.

# yum install epel-release
# yum erase ambari-agent
# yum install -y ambari-agent

Then edit the ambari-agent.ini, and under the Server change the host to your Ambari server FQDN

vi /etc/ambari-agent/conf/ambari-agent.ini

[server]
hostname={your.ambari.server.hostname}

Then start the agent.

This should resolve the problem
