Look at GossipingPropertyFileSnitch
(http://www.datastax.com/documentation/cassandra/2.0/webhelp/index.html#cassandra/architecture/architectureSnitchesAbout_c.html)
and just use simple seed provider as described in the Datastax multi dc
documentation.
That way for each new node you just need to define its dc / rack and it will
use gossip to discover this information about other nodes.

Hello everyone,
I have a cassandra cluster running at amazon. I am trying to add a new
datacenter for this cluster now, outside AWS. I know I could use multiregion,
but I would like to be vendor free in terms of cloud.
Reading the article
http://www.datastax.com/docs/datastax_enterprise3.2/deploy/multi_dc_install,
it seems I will need to start using PropertiesFileSnitch instead of Ec2Snitch
to do what I want. So here it comes my question:
If I set all the seeds on my property file, what will happen if I need to
add mores machines and/or seeds to the cluster? Will I need to change the
property files on all the nodes of my cluster, or just on the new node?
Best regards,
Marcelo Valle.
