Hi Dave,
Thanks for ur reply..I tried using elastics ips.
And below is the configuration of the cassandra.yaml in both the nodes.
seeds:
- 50.18.60.117
- 175.41.143.192
Now when i run cassandra i get following exception

I am able to ping both the nodes through public ips.

Re: Cassandra nodes on EC2 in two different regions not communicating
internal EC2 ips (10.xxx.xxx.xxx) work across availability zones (e.g.,
from us-east-1a to us-east-1b) but do not work across regions (e.g.,
us-east to us-west). To do regions, you must use the public ip address
assigned by amazon.
Himanshi, when you log into 1 node, and telnet to port 7000 on the other
node, which IP address did you use - the 10.x address or the public ip
address?
And what is the seed/non-seed configuration in both cassandra.yaml files?

The internal Amazon IP address is what you will want to use so you don't
have to go through DNS anyways; not sure if this works from US-East to
US-West, but it does make things quicker in between zones, e.g. us-east-1a
to us-east-1b.

Try using the IP address, not the dns name in the cassandra.yaml.
If you can telnet from one to the other on port 7000, and both nodes have
the other node in their config, it should work.

Thanks Dave but I am able to telnet to other instances on port 7000

ec2-50-18-60-117.us-west-1.compute.amazonaws.com ring... I can see only
one node.
Do we need to configure anything else in Cassandra.yaml or
Cassandra-env.sh ???

Re: Cassandra nodes on EC2 in two different regions not communicating
If you login to one of the nodes, can you telnet to port 7000 on the other
node?
If not, then almost certainly it's a firewall/Security Group issue.
You can find out the security groups for any node by logging in, and then
running:
% curl "http://169.254.169.254/latest/meta-data/security-groups";
Assuming that both nodes are in the same security group, ensure that the
SG is configured to allow other members of the SG to communicate on port
7000 to each other.

Hi,
I am new to Cassandra. I m running Cassandra on EC2. I configured
Cassandra cluster on two instances in different regions.
But when I am trying the nodetool command with ring option, I am getting
only single node.
How to make these two nodes communicate with each other. I have already
opened required ports. i.e 7000, 8080, 9160 in respective
security groups. Plz help me with this.
Regards,
Himanshi Sharma
