Description

Hello, we're using vanilla Cassandra in an EC2 environment and I just tested upgrading from 1.2.0 to 1.2.1 on two test instances. Cassandra fails to start because it's unable to load the Ec2Snitch. Version 1.2.0 was working OK. I have tried this on uninitialized/empty instances and received the same result. Cassandra successfully starts when switching to SimpleSnitch. Log output is below. We're using the official debian package from apache.org. Please let me know if you need any more details, thanks!
