Thank you Chiru for the reply. I am configuring single datacenter. I changed it to SimpleSnitch. However, I am getting the same error.

Hi Sundeep,

Can you please confirm, are you configuring two nodes in different Datacenters?

If you are configuring on single datacenter with two nodes,then please change the endpoint_snitch  from  RackInferringSnitch to SimpleSnitch and restart the clusters.

Regards,
Chiru

Hi,

I am trying to setup multi-node Cassandra cluster (2 nodes). I am using apache-cassandra-2.0.4. I am able to start Cassandra on the seed node. But, when I am trying to start it on the other node it starts and fails in few seconds. I can see the following in my error log: 

"ERROR 03:23:56,915 Exception encountered during startup
java.lang.RuntimeException: Unable to gossip with any seeds "


I am able to telnet from node 1 to node 0.

telnet 10.2.252.0 9000
Trying 10.2.252.0...

When I am trying to start Cassandra on node 1 it fails and the log shows:
