Discovery.zen.ping.unicast.hosts?

Elastic Stack Elasticsearch

Hi I am reading the document: https://www.elastic.co/guide/en/elasticsearch/guide/1.x/_important_configuration_changes.html

At the bottom of the document, it says I should list the three dedicated master as the value of discovery.zen.ping.unicast.hosts

Can I add a load balance ELB here?

Yes, you can do that.

discovery.zen.ping.unicast.hosts: "elb name" or discovery.zen.ping.unicast.hosts: ["elb"] ?

which format should i use?

You can use either AFAIK, but the docs refer to an array so use that.

Also you should upgrade from 1.x! :slight_smile:
