Hello,

I have an ECK with 1 kibana + 4 nodes Elasticsearch + 1 Logstash.  
I am using hot warm cold rotation.

I would like to change my design.  
I would like to change for 1 kibana + 3 nodes HOT + 3 nodes WARM + 3 nodes COLD + 1 Logstash  
But normally, I need a master too. 1 Master is enough ?  
Do you think it's good as design ?

Thanks,

---

Hi Chloe,

it is good practice to limit the number of master-eligible nodes in the cluster to three

I'll send you a link to the documentation that might clarify the whole situation.

It is not enough, you need at least 3 master to have a resilient cluster.
