Elasticsearch network host cant be set?

I just ran into this error too. Looking at the code, it looks like once you decide to explicitly set network.host, we assume you're doing this because you've moved beyond a simple dev instance and are setting up something that's more production-like.

Since we are assuming this is now a production-like environment, we now enforce some of these checks that we otherwise wouldn't in a simple dev installation.

elastic/elasticsearch/blob/e772b6d924c8e53c2ab1744faddc610baf1b6287/core/src/main/java/org/elasticsearch/bootstrap/BootstrapCheck.java#L46

import java.nio.file.Files;

import java.util.Locale;


/**
* We enforce limits once any network host is configured. In this case we assume the node is running in production
* and all production limit checks must pass. This should be extended as we go to settings like:
* - discovery.zen.ping.unicast.hosts is set if we use zen disco
* - ensure we can write in all data directories
* - fail if the default cluster.name is used, if this is setup on network a real clustername should be used?
*/
final class BootstrapCheck {


   private BootstrapCheck() {
   }

Hope that helps,
Peter
