I just would advise against it because it's going to be difficult to narrow
down what's causing problems. For instance, if you have "Node A" which is
performing GC, it will affect query times on "Node B" which is trying to
satisfy a quorum read. "Node B" might actually have very low load, and it

We are currently trialling SmartOS with Cassandra and have seen some pretty
good results (and the mmap stuff "appears" to work). As Rob said, if this is
production cluster, run with linux… there will be far less pain.
If you are super keen on running on something different from linux in
product
Its quite possible its well tricked out for Linux.
My major issue with Linux has been that its TCP/IP stack is nowhere near as
scalable as Solaris' for massive numbers of simultaneous connections. But
thats probably less of an issue with a Cassandra node then it has been with
the game servers I'v

Is this your first cluster? Have you run older versions of Cassandra? Any
specific resource tuning?
Thanks all. We are unab

What issues are you running into with CentOS 6.4/5? I’m running 1.2.8 on
CentOS 6.3 and Java 1.7.0-25, and about to test with 1.7.latest.

Hi all,
I was wondering what operating systems and versions people are running with
success in production environments? 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?!)?
