Re: Opscenter help?
- Were you running a mixed EL5/EL6 environment? - What exact version of Cassandra were you upgrading from? As for SE, you have to amass a bit of their magic points before you can start to take more actions (tagging, down-voting, etc).

Re: Opscenter help?
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.

You don't need any reputation points to ask a new question with an existing tag - just type opscenter in the Tags box under the question. Otherwise, how would any new user ever be able to ask a question and have it tagged?! -- Jack Krupansky -Original Message- From: Drew from Zhrodague Sent: Thursday, March 13, 2014 9:29 AM To: user@cassandra.apache.org Subject: Re: Opscenter help?

Re: Opscenter help?
I'm happy to help here as well :) Can you give some more information? Specifically: What exact versions of EL5 and EL6 have you tried? What version of OpsCenter are you using? What file/dependency is rpm/yum saying conflicts with sudo? Also, you can find the OpsCenter documentation here http://www.datastax.com/documentation/opscenter/4.1/index.html, although this isn't an issue I've seen before. -Nick On Wed, Mar 12, 2014 at 1:51 PM, Drew from Zhrodague drewzhroda...@zhrodague.net wrote: I am having a hard time installing the Datastax Opscenter agents on EL6 and EL5 hosts.

Re: Opscenter help?
I have seen the conflicts with sudo error but that was with 3.X rpm on the amazon ami, i was how ever able to install it from the tar ball. As Nick has pointed out, the versions of OS and Opscenter will help in looking at this.
