Subject Cassandra on AWS across Regions
Date Tue, 29 Jun 2010 02:18:06 GMT
Hi All,

We have a Cassandra cluster setup with 2 EC2 m1.large machines, one is
running in us-east zone whereas 2nd one is running in us-west zone. As part
of Seed section, I provided each other's node's EC2 public DNS entry in each
of storage-conf.xml. but when I ran nodetool command, I am not finding both
ec2 nodes as part of Ring which is because they have registered each other
using their Private IP address for receiving gossip messages and those
private ips won't be reachable across zones. So what should be done to make
both nodes to be registered with each other with their Public DNS/IP address
instead their Private IP. This is not a problem if we setup the entire
cluster with in the same region and zones (US-EAST), cuz they can
communicate with private IP. Can any one share What is the recommended
approach here?
