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

Hi,
You always want an odd number of master nodes (often 3), so I would
therefore recommend setting three of the four nodes to be master eligible
and leave the fourth as a pure data node. This will prevent the cluster
getting partitioned into two with equal number of master nodes on both
sides
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 recom
Take a look at these pages -

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

I am in need of help on setting up a 4 node elasticsearch servers. I have
installed and configured ES on all 4 nodes but I am lost as to what the
