Todd Nine commented on CASSANDRA-4026:
--------------------------------------
Could we create a new snitch that corrects the problem and deprecate the
existing snitches? This way people can migrate if they choose to, or keep the
old snitches if it does not affect them.
> EC2 snitch incorrectly reports regions
> --------------------------------------
>
> Key: CASSANDRA-4026
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4026
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.8
> Environment: Ubuntu 10.10 64 bit Oracle Java 6
> Reporter: Todd Nine
> Assignee: Vijay
>
> 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.
