@Joseph Sorry for the delay in response here. Overlaying Cloudera Manager over an existing CDH cluster is a tricky operation and requires care, but can be done. Our own Eric Sammer posted this thread on Quora a while back detailing the overall steps. If you have follow up questions after reading that, we're happy to assist.

@yyx for your GC settings question: this is not a factor of CDH at all. This is something that your JVM controls. What JDK are you using?
2nd Question: I believe this thread on our mailing list solves it.
Your final questions about the property settings are a bit confusing to me. I'm not seeing how the Hlog settings relate to lowerLimit of memstore, but I can tell you what they default to in a Cloudera Manager cluster:
hlog.blocksize always defaults to your HDFS block size, unless you override it.
maxlogs defaults to 32
lowerLimit defaults to .35
upperLimit defaults to 0.4

OK, apparently this is a misconfiguration in your yum repos. I'm not sure what error you are getting when trying to install postgresql-server, but our installer will use yum to do that and is apparently not able to contact the RHEL repos.

Ah, ok. You are correct that you are not supposed to have to pre-install postgresql for Path A. It's possible that there the latest version of CM has dependencies that are incompatible with RHEL 5.7, even though the document I linked claims support for RHEL 5.7.
I will investigate and get back to you.

As per the Installation Requirements of CM 4.7.3, PostGres 8.1 or higher is required. You are on an older version of RHEL and therefore do not have a new enough version of PostGres. You can try the following command and see if you can get postgres upgraded to an acceptable version:
yum update postgresql-server

What is the value of the "server_host" property inside this file?
/etc/cloudera-scm-agent/config.ini
Also, what does the 'hostname' command return? I would grep the results of the hostname command from /etc/hosts and make sure your host's name isn't on the loopback line (127.0.0.1) of /etc/hosts.

@foxz88 this is odd as the FQDN for the "localhost" loopback address should not affect anything with your actual host's FQDN or IP. Can you take a look at what is returned from the "hostname" command? I suspect your host is configured to call itself "localhost.localdomain" and that's why your services were trying to bind to that hostname and also why removing that from /etc/hosts freed you up.
The file /etc/sysconfig/network should contain a "HOSTNAME=" tag, which in your case should be listed as "homer.larim.polymtl.ca" in order for your services to work properly. Note: it will require a reboot after you change that file in order for the new hostname to take effect.

What does the following command return on your system?
