FAQ
Hi,

I have one machine with OS RHEL 6.3. I got Cloudera Manager installed on
it. And I was trying to install CDH4 on the same machine as its a dev
environment.
The IPadrress is found, however installation keeps failing at a point
'MainThread agent ERROR Could not determine hostname or IPAddress,
proceeeding. gaierror :[Errno -2] name or service not known.


Is this happening because installing on one machine automatically via CM is
not supported?

    Installing on one machine via CM is fully supported and does work (I
    have a VM running it). The error you've received seems network config
    related.

    Could you post the outputs of each of these commands?

    $ hostname
    $ hostname -f
    $ cat /etc/hosts
    $ ifconfig

    Thanks Harsh.
    I set my fully qualified domain name, and rebooted, and I managed to
    install Cloudera agent on the same machine
