Hello Sundeep

It seems that in both configs of your nodes you are using the same hosname as seeds value.

You have to enumerate all nodes in your cluster.

Best wishes,
Ilya

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...
Connected to 10.2.252.0.

cassandra.yaml

node 0: (sk.r252.0)(seed)

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