Brandon Williams commented on CASSANDRA-7147:
---------------------------------------------
CASSANDRA-7132 didn't need this because of this statement: "Due to the
cross-regional availability of networks on Google, there is no need for a
separate Multi-region Snitch to compensate for cross-region communication. All
communication can occur on private ip addresses within the same logical
network." so I'm wondering if cloudstack is any different here.
> Add a new snitch for Apache Cloudstack platforms

> Key: CASSANDRA-7147
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7147
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Environment: Virtual machine on Apache Cloudstack environments
> Reporter: Pierre-Yves Ritschard
> Priority: Minor
> Fix For: 2.0.8, 2.1 beta2
>
> Attachments: 0001-initial-work-on-a-cloudstack-snitch.patch
>
>
> The attached patch adds a new Snitch that queries meta data for a host on
> Apache Cloudstack environments. Since the metadata service is colocated with
> the DHCP service in Cloudstack, common lease file locations are looked up to
> retrieve.
> Since zone naming is freeform in Apache Cloudstack, the widely used
> <country>-<location>-<az> notation is assumed.
> The patch includes a simple unit test and has been tested on exoscale.ch, a
> public cloud based on Apache Cloudstack
