Cloudera SCM fails because it is not able to use yum to download and install JDK.

So far I have seen it always tries to do that.

You can update yum repository on the machines yourself, depending on what version of Linux you are using.

Here is example using RHEL / OEL 5:

# This adds Oracle Yum repo
cd /etc/yum.repos.d/
wget http://public-yum.oracle.com/public-yum-el5.repo

# This adds Fedora EPEL yum repo
yum remove epel-release-5-4
rpm -Uvh http://mirrors.kernel.org/fedora-epel/5/x86_64/epel-release-5-4.noarch.rpm

See if you can install JDK manually.

[Edit:]

Check if you are able to do the following with out issues:

python
>>> import urllib
>>> x = urllib.urlopen('http://archive.cloudera.com/redhat/cdh/3/repodata/repomd.xml')
>>> x.getcode()
200
>>> print x.readlines()
