Error while starting a Cassandra Cluster on Amazon EC2

Question

I am trying to set up a 3-node cassandra cluster on amazon EC2 instances yet i am having an issue while trying to startup the cluster. Here are my configuration options:

Node-1

private-ip a.a.a.a
public-ip b.b.b.b

Node-2:

private-ip c.c.c.c
public-ip d.d.d.d

Node-3:

private-ip e.e.e.e
public-ip f.f.f.f

For each node I have chosen both Node-1 and Node-2 to be seeds. Therefore on all the cassandra.yaml files i have added the nodes public IPs.

Moreover, for each instance I have set the following properties:

listen_address private-ip
broadcast_address public-ip
rpc_address 0.0.0.0
broadcast_rpc_address public-ip
endpoint_snitch Ec2Snitch
auto_bootstrap false

Yet while trying to initialize the first node, the following exception happens:

ERROR [main] 2016-12-26 17:08:55,336 CassandraDaemon.java:654 - Exception encountered during startup

Any idea on what I am doing wrong?

Did you manage to figure out what you did to resolve this? It would be great to have closure as I am stuck in a similar situation — Aamir Mushtaq

Can you try with rpc_address and listen_address as eth0.

We have built cassandra cluster on EC2 nodes with EC2Snitch and with eth0 and it works perfectly.
