Ec2MultiRegionSnitch throws AssertionError on EC2
-------------------------------------------------

                 Key: CASSANDRA-3000
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3000
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.8.2
         Environment: build version: apache-cassandra-2011-08-07_02-23-42

OS: Ubuntu 10.04.2 LTS \n \l

# uname -a
Linux ip-10-227-143-202 2.6.32-312-ec2 #24-Ubuntu SMP Fri Jan 7 18:30:50 UTC 2011 x86_64 GNU/Linux

            Reporter: Gourav Shah


I found Ec2MultiRegionSnitch patch at https://issues.apache.org/jira/browse/CASSANDRA-2452


However, I could not find any documentation on how to get it working, which address to use
as seed, listen and thrift addresses. I used the following, 

seed_address     = Public DNS of the seed node 
listen_address   = Public DNS of the cluster node
rpc_address      = 0.0.0.0
endpoint_snitch: org.apache.cassandra.locator.Ec2MultiRegionSnitch


When I try to start cassandra, I get the following error:
