I have to reply to myself, since there were no helpful responses.
Perhaps these notes can help other people from pulling their hair out.
When installing the datastax-agent on EL6, it is required to do a bunch
of things to correct a bunch of stuff.
[] yum install mx4j log4j datastax-agent - do not install
opscenter-agent, this is a stale/old package it seems. Ignore log4j
errors on starting the agent. You may have to download the
datastax-agent and force an install via rpm - it will conflict with
sudo, because of the existance of the dir, /etc/sudo.d/
[] You may have to fix the UID/GIDs. Older packages set the cassandra
UID/GID both to 217. Installing the agent conveniently mutilated them
for us. I had to change the datastax-agent UID and GID back to 215,
cassnandra UID/GID back to 217, and re-chown these directories:
() /var/log/cassandra
() /var/lib/cassandra
() /var/run/cassandra
() /var/log/datastax-agent
() /var/lib/datastax-agent
() /var/run/datastax-agent
[] If you can't get datastax-agent to install via opscenter
automatically, you'll need to configure it manually:
() yum install datastax-agent
() mkdir -p /var/lib/datastax-agent/conf/
() echo "stomp_interface: 10.113.143.189" >>
/var/lib/datastax-agent/conf/address.yaml
[] restart the datastax-agent, and it should now work.
Cassandra Upgrading notes:
[] We upgraded packages from apache-cassandra11 to cassandra12 - the
new RPM is not configured as a replacement for the old one.
[] Check your directory permissions as above, and in your data-storage
dir.
[] If you use a symlink or mount point to store your actual data on, it
will be overwritten with an empty directory. Make sure to fix this, or
you'll be in for a surprise.
[] Make sure to install Sun Java - we use alternatives --config java,
but have to do this to set the default JAVA_HOME: echo "export
JAVA_HOME=/usr/java/jdk1.7.0_51" >> /etc/profile.d/other-java.sh
I wasn't able to properly tag my questions on StackExchange, which
required me to have a reputation value above 300. I dunno why it brought
up that red box stating that I needed to have over 300 points to add a
new tag, those tags seem to be in there today.

Datastax has move their forums to Stack Exchange, which seems to be a
waste of time, as I don't have enough reputation points to properly tag
my questions.
The agent installation seems to be broken:
[] agent rpm conflicts with sudo
[] install from opscenter does not work, even if manually
installing the rpm (requres --force, conflicts with sudo)
[] error message re: log4j #noconf
[] Could not find the main class: opsagent.opsagent. Program will
exit.
[] No other (helpful/more in-depth) documentation exists
