Subject Fwd: Unable to gossip with any seeds
Date Mon, 03 Feb 2014 08:47:20 GMT
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.
Escape character is '^]'.
^]
Connection closed by foreign host.


*cassandra.yaml*

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

cluster_name: 'DataCluster'
num_tokens: 256
initial_token: 0
seeds: "sk.r252.0"
storage_port: 9000
ssl_storage_port: 9001
listen_address: sk.r252.0
rpc_address: 0.0.0.0
rpc_port: 8192
endpoint_snitch: RackInferringSnitch

node 1: (sk.r252.1)
cluster_name: 'DataCluster'
num_tokens: 256
initial_token: 4611686018427387904
seeds: "sk.r252.0"
storage_port: 9000
ssl_storage_port: 9001
listen_address: sk.r252.1
rpc_address: 0.0.0.0
rpc_port: 8192
endpoint_snitch: RackInferringSnitch


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