Re: Help with 4 node cluster
You can have 4 master eligable if you want , just set discovery.zen.minimum_master_nodes to 3 to ensure a quorum. But ideally as Christian mentioned, it's best to have an uneven number of masters.

Re: Help with 4 node cluster
you can make all nodes as master + data by setting following in elasticsearch.yml file. i dont think/know if you can setup 2 nodes as primary in cluster. For each index, you can set number of replica as 1 or more, so ES will automatically move them to different nodes than primary shard. i recommend using unicast for discovery as shown below if you have static IPs. node.master: true node.data: true discovery.zen.ping.multicast.enabled: false discovery.zen.ping.unicast.hosts: [IP1, IP2] On Wednesday, February 18, 2015 at 5:39:54 AM UTC-6, sysads wrote: Hi I am in need of help on setting up a 4 node elasticsearch servers.

Re: Help with 4 node cluster
Take a look at these pages - http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/deploy.html Also there is not really any point in forcing shard types on specific machines, unless you want to leverage some kind of awareness. A primary and replica shard are the same thing other than a metadata flag that differentiates them.
