If you're using a network transport in your code, this won't work, as node.local gives you a LocalTransport only:

The trick then is to set

discovery.zen.ping.multicast: false

in your elasticsearch.yml which will stop your node looking for any other nodes.

I'm not sure if this prevents other nodes from discovering yours though; I only needed this to affect a group of nodes with the same settings on the same network.
