    I just recently installed HDP with 100% success, all green lights in Ambari. However, I just ran a yum update on one of my data nodes and now ambari fails to start. It looks like a newer version of ambari agent was installed in this yum update process.

    Any ideas what could have happened?

    it is not good to have one agent on the different version from the server and other agents.
    Please, go ahead stop ambari-server and all ambari-agents and perform “yum update ambari-server” and “yum update ambari-agent” on all your nodes.
    Then restore saved configurations and start all the processes.

    This way you will be on the latest Ambari version, which was just released few days ago.

    Thank you!

    I did a “yum update”




    Hi Ray,
    Thanks for the information. Did you do a yum update with no parameters passed or did you pass in parameter?

    Ok, so I think I figured it out.

    After the the new version of ambari(ver- was installed, it seems as though the /etc/ambari-agent/conf is copied to

    This causes the ambari-agent to no longer have a ambari-agent.ini

    Once I copied the to /etc/ambari-agent/conf/ the agent started successfully.
