Description

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.
