Hi all,

I check the threads in this group, and I setup hostname correctly, I can
use python to get correct hostname and ip address, but still failed to
connect to supervisord.conf, why?

This is the log:

    This log output does not show anything is actually wrong. That error you
    see is the Agent failing to connect to an existing supervisord - but that's
    ok, the Agent will start it, and you see that further down in the log:

    Is there anything actually not working that makes you think there's a
    problem?

    Hi Philip,

    Thanks for your answer. As you say, even there is an error in the log, I
    can still connect to the supervisord through web ui.

    But cloudera manager doesn't work, It complains it cannot receive signal
    from agent, as a result, I cannot install CDH in the agent machine.

    Do you have a firewall configured, preventing the agents connecting to the
    server? If you look at the agent's config file at
    /etc/cloudera-scm-agent/config.ini, is the server hostname specified there
    one that works for your server? If you have a complex DNS setup, it might
    end up being wrong.

    Hi Phil,

    I try them too, and it still fail through CM Wizard. It seems that the
    supervisord will failed at first time and run successful the second time.

    But I found that I can run "Add Hosts to Cluster", and choose the existed
    host, and install the parcel.
    Finally I can install hadoop service successfully. Though it takes me one
    week to finish it.

    Thanks.
