The HA documentation is a little confusing in that it suggests JM registration and discovery is done via Zookeeper, but it also recommends creating a static `masters` file listing all JMs. The only use I can currently see for the masters file is by the `start-cluster.sh` script. Thus, if we're not using that script, do we need the masters file at all?
- masters file only needed when using start-cluster.sh script? David Corley
