--------------------------------------
Thanks for the information! Will submit a patch instead.
(Would be great if this were noted in
[GitTransition|http://wiki.apache.org/cassandra/GitTransition].)
> YAML network topology snitch supporting preferred addresses

> Key: CASSANDRA-5339
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5339
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Eric Dong
> Priority: Minor
>
> In order to support having a Cassandra cluster spanning multiple data
> centers, some in Amazon EC2 and some not, I'm submitting a YAML network
> topology snitch that allows one to configure 'preferred addresses' such as a
> data-center-local address. The new snitch reconnects to the node via the
> preferred address using the same reconnection trick present in
> Ec2MultiRegionSnitch.
> I chose a new YAML format instead of trying to extend
> cassandra-topology.properties because it is easier to read and allows for
> future extensibility.
> Pull request to follow.
