I have 3 nodes.
How do I set discovery.zen.ping.unicast.hosts? Do I set all of the host names for all nodes into the config file for each node?
Do I set node.master: true for 2 of them or 1, to avoid split-brain?
Do I set node.data : true for 2 of them or 1?
What should I set for discovery.zen.minimum_master_nodes? 2, or 1?
The documentation leaves me a confused as what to use.
