Subject [jira] [Commented] (CASSANDRA-4026) EC2 snitch incorrectly reports regions
Date Tue, 26 Aug 2014 21:28:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14111368#comment-14111368
] 

Gregory Ramsperger commented on CASSANDRA-4026:
-----------------------------------------------

Not to reopen ancient tickets, but code was added in CASSANDRA-5897 to pull in SnitchProperties.
Would it not be desirable to address this by looking at an additional property and choosing
between legacy naming and a full, consistent with other EC2 APIs, naming scheme?

Something similar to this commit [https://github.com/ramsperger/cassandra/commit/bf1ee0251e5cf46b8af28282e22c4fbf29d85f33?w=1]?

> 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.
