Hi, would there be much involved in discovery of instances and their properties when they become available? I would like to add functionality to my application that would require zeroconf in determining the instances of elastic search thar are available and what ports they are using to direct requests. Thanks ---

Hi, I think the best way would be to use Nodes Info REST API: [http://www.elasticsearch.com/docs/elasticsearch/rest\_api/admin/cluster/nodes\_info/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/admin/cluster/nodes_info/) Note that current doc needs to be updated as in current version the Elasticsearch gives you a lot more info including http\_address for each node that you can use to talk to particular node.
