Just double checking: Is discovery.zen.minimum\_master\_nodes still valid when using the EC2 discovery plug-in or does the syntax change to something like discovery.ec2.minimum\_master\_nodes ? It looks like it's the former to me and I'm about to test it myself but I just wanted to do a sanity check. -GS -- ---

Answering my own question: yes, discovery.zen.minimum\_master\_nodes works with the AWS plugin, not just the default Zen Discovery mode. I guess the AWS plug-in just builds on top of Zen? Anyways, it works.

Yes, it does, and yes its built on top of zen. (Just revalidating your answer 🙂 ).
