This /is/ our first cluster. We've upgraded one-over-one since 2.0.2 (our initially deployed version), doing rolling updates across the rings.
No especial resource tuning save turning off SELinux and the usual (disabling swap, separate disk for commit logs, data and the OS).

Have you run older versions of Cassandra? Any specific resource tuning? Thanks all. We are unable to bootstrap nodes and are considering creating a fresh cluster in hopes this is some how data related.

We have just a couple of pre-production rings (Dev and Test) meaning nothing we have has received particularly intense utilization.

We are using C* 1.2.13 and have had issues using CentOS 6.4/6.5. Are others using that OS? What would people recommend? What about Java 6 vs 7 (specific versions?!)?
