Subject [jira] [Comment Edited] (CASSANDRA-5155) Make Ec2Region's datacenter name configurable

-----------------------------------------------------------------

This change simply appends a string to the end of the EC2 region name. It piggybacks off the
conf/cassandra-rackdc.properties file (I didn't think this required a new config file).

This patch only appends to create a unique datacenter name, however, I"m not sure how extensible
function needs to be.

> Ec2Region sets a one-to-one mapping between the EC2 region name and the datacenter name.
I'd like to be able to make the DC name configurable.
> The use case here is running DataStax Enterprise in EC2 and the need to have a plain
c* datacenter and a c*/solr cluster datacenter running within the same region (for the same
cluster). Can't make the two (or more) datacenters in the region with the one-to-one mapping
of EC2 region to c* DC.
