Hmmmm looking a bit deeper - in the Cluster class, I see the ability to get a list of IPs per ROLE. However... I have multiple possible instances for each and every ROLE, and every role has to know its own IP/hostname. The configuration file requires this.
I looked at how the Hadoop configs work, and they assume one instance of certain types of nodes. Is this a limitation in druid - or can I just use something simple, like `hostname` - although I'm not sure how to get it back into my configuration builder in Java?
