Subject Looking for a fully working AWS multi DC configuration.
Date Wed, 05 Jun 2013 13:48:59 GMT

We use to work on a single DC (EC2Snitch / SimpleStrategy). For latency
reason we had top open a new DC in the US (us-east). We run C* 1.2.2. We
don't use VPC.

Now we use:
- 2 DC (eu-west, us-east)
- EC2MultiRegionSnitch / NTS
- public IPs as broadcast_address and seeds
- private IPs as listen_address

Yet we are experimenting some troubles (node can't reach itself, Could not
start register mbean in JMX...), mainly because of the use of public IPs
and the AWS inter-region communication.

If someone has successfully setup this kind of cluster, I would like to
know, if our configuration is correct and if I am missing something.

I also would like to know what ports I have to open and either where I have
to open them from.

Any insight would be greatly appreciated.
