Hi,

I would like to know if 3-node cluster is the desired setup for Elasticsearch? I have this type of setup since I'm configuring X-Pack for this cluster.

Cluster: TestES

[node.name](http://node.name): ENode1  
node.master: true  
node.data: false  
node.ingest: false

[node.name](http://node.name): ENode2  
node.master: true  
node.data: true  
node.ingest: false

[node.name](http://node.name): ENode3  
node.master: false  
node.data: true  
node.ingest: true

But If have a 2-node cluster there should be two masters and 2 data nodes? or is it possible to have this type of setup..

Cluster: TestES

[node.name](http://node.name): ENode1  
node.master: master  
node.data: true  
node.ingest: false

[node.name](http://node.name): ENode2  
node.master: true  
node.data: true  
node.ingest: true

Will this affect the performance of Elasticsearch if cluster is only 2-node?

Thanks!

Set all 3 nodes master:true and don't use only 2 nodes to avoid cluster stopping or split brain issues.
