> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.8
> Environment: Ubuntu 10.10 64 bit Oracle Java 6
> Reporter: Todd Nine

> Currently the org.apache.cassandra.locator.Ec2Snitch reports "us-west" in
> both the oregon and the california data centers. This is incorrect, since
> they are different regions.
> California => us-west-1
> Oregon => us-west-2
> wget http://169.254.169.254/latest/meta-data/placement/availability-zone
> returns the value "us-west-2a"
> After parsing this returns
> DC = us-west Rack = 2a
> What it should return
> DC = us-west-2 Rack = a
> This makes it possible to use multi region when both regions are in the west
> coast.
