We have upgraded the Ambari Server and agent from 2.2.1.1 to 2.4.0.1-1
Ambari Server and Agent on the same server is running fine. We have additional 2 nodes and we are getting following error on both the nodes while starting Ambari agent.
- we have updated ambari-agent.ini to point to Ambari Server
- We do not see /var/log/ambari-agent/ambari-agent.log file created.
- We have tried uninstall and re-install of the ambari-agent but still getting same following error.

please uninstall ambari-agent, remove all associated directories like /etc/ambari-agent, /var/lib/ambari-agent, etc.
Then delete the following directory
/usr/lib/python2.6/site-packages/ambari-agent
after that install ambari-agent again.

I am working with Raviraj and performed the recommended steps on his behalf, issue still exists, different error message this time though.
As suggested:
Uninstaled ambari-agent, removed following directories and successfully re-installed ambari-agent:
/etc/ambari-agent
/var/lib/ambari-agent,
/var/run/ambari-agent
/usr/lib/amrbari-agent
/usr/lib/python2.6/site-packages/ambari-agent
While starting the agent it now throws different error:
Starting ambari-agent Verifying ambari-agent process status... ERROR: ambari-agent start failed. For more details, see /ambari-agent.out: ==================== Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/ambari_agent/AmbariAgent.py", line 24, in <module> from Controller import AGENT_AUTO_RESTART_EXIT_CODE File "/usr/lib/python2.6/site-packages/ambari_agent/Controller.py", line 41, in <module> from ambari_agent.ActionQueue import ActionQueue File "/usr/lib/python2.6/site-packages/ambari_agent/ActionQueue.py", line 37, in <module> from ambari_commons.str_utils import split_on_chunks ImportError: cannot import name split_on_chunks ====================
The ambari-agent.out file also show same above messages that we see in console
