FAQ
Hi,

I am adding Hosts using CM. But after installation of hosts, when I go for
adding services, it says, "Server Error", No hosts. Please advise.

Regards,
Shouvanik

    CM 3.7 is like the stone age compared with CM 4.1 (the current version).
    Could you upgrade to CM 4.1 and try again? Just install the packages and
    restart the CM server. It'll take care of the rest.

    (I recall that error message being a lot more helpful in CM 4.1.)

    I could upgrade to 3.7.8 but I am stuck up with not able to see any hosts
    coming up.

    What can be the possible reason?

    I am getting errors like this below:

    TaskTracker at http://127.0.0.1:4867 is not responding: [Errno socket
    error] [Errno 111] Connection refused.

    [01/Dec/2012 11:17:29 +0000] 10436 MainThread agent INFO Logging
    to /var/log/cloudera-scm-agent/cloudera-scm-agent.log
    Error: Another program is already listening on a port that one of our HTTP
    servers is configured to use. Shut this program down first before starting
    supervisord.
    For help, use /usr/lib64/cmf/agent/src/cmf/../../build/env/bin/supervisord
    -h


    Please help.! I am banging my head to get the hosts up and running.

    Rgds,

    There is a port conflict at 9000. Look at
    /etc/cloudera-scm-agent/config.ini and check "listening_port". You can do
    `lsof -i :9000' to see what other process has that port. And you can also
    change the config.ini file to use another port. Restart the agent
    afterwards.

    Go to CM -> Hosts. And verify that the agents are sending in heartbeats.

    You can upgrade to 4.1.1. It's at http://archive.cloudera.com/cm4/.
    Instructions here:
    https://ccp.cloudera.com/display/FREE4DOC/Upgrade+from+Cloudera+Manager+3.7.x+to+Cloudera+Manager+4.0
    .

    (4.1.1 has a lot of bug fixes and new features over 3.7. And the 3.7.x line
    will not have regular point releases any more. You'll be doing yourself a
    big favour to upgrade.)
