Subject [jira] [Commented] (CASSANDRA-7147) Add a new snitch for Apache Cloudstack platforms
Date Sat, 03 May 2014 17:07:15 GMT


Pierre-Yves Ritschard commented on CASSANDRA-7147:

The rationale is that there are now large providers based on Cloudstack (disclaimer: I'm CTO
at one of them) who follow the standard notation. This gives the same flexibility than you
get with EC2Snitch or GoogleCloudSnitch

I don't know how openstack handles this.

> 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, a public cloud
based on Apache Cloudstack
