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

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:
