----------------------------------
Hi Brandon,
"Can you explain why that's necessary? It seems to me if the node doesn't know
it's own BA when it starts up, it's already going to get into trouble."
-- This is Just for automation, Snitch will be initialized when
DatabaseDescripter is initialized hence it will be safe and the Snitch is
called only for the first time to set the BA... The fall-back if BA is not
available then use getLocalAddress()
-- It Can also be automated outside cassandra too... let me know if you still
think it is bad i can remove that logic.
For the rest, I will rebase it once again if you say we are good to go...

> A new config parameter, broadcast_address
> In a cluster setup where one or more nodes is behind a firewall and has a
> private ip address, listen_address does not allow the hosts behind the
> firewalls to be discovered by other nodes.
> Attached is a patch that introduces a new config parameter broadcast_address
> which allows Cassandra nodes to explicitly specify their external ip address.
> In addition, this allows listen_address to be set to 0.0.0.0 on the already
> firewalled node.
> broadcast_address fallsback to listen_address when it is not stated.
