Vijay updated CASSANDRA-4026: ----------------------------- Comment: was deleted (was: I ran through it a while ago. But the problem is that we cannot change the settings on the current live clusters which uses Ec2MultiregionSnitch or Ec2Snitch without taking a downtime. (If we change EC2Snitch/Ec2Multiregion snitch, we also need to change the schema for the existing cluster). Option 1: Leave the existing snitch as it is and add a new snitch. Option 2: Parse for us-west-1 as us-west and parse us-west-2 as us-west2, as us-west-2 is fairly new it wont affect a lot of us? Brandon, Thoughts? ) > 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. -- This message is automatically generated by JIRA.
