How to disable multicast zen discovery in elasticsearch 5

Elastic Stack Elasticsearch

Hi,

I am trying to setup 3 master eligible nodes and the setting discovery.zen.ping.multicast.enabled: false no more exists in elasticsearch 5. In elasticsearch 2.3, it was working fine. How can I do it in elasticsearch 5?

Thank you.

You don't need to worry about it, the default is unicast.

In fact the setting you defined in 2.x was silently ignored as multicast was only available as a plugin.
5.0 rejects now unknown settings.
