Get Active nodes' addresses

In a clustered environment with HA, is there any API which returns the address of the active Overlord, Coordinator and Broker nodes?

I assume this is implemented for Overlord since Tranquility guesses it using Finagle and Curator service from Zookeeper.

Is there something that is exposed directly? Or if not, is there a workaround?



The only place is the service discovery managed by zookeeper node.
