I have a two-node scale ES cluster. In the configuration of the ES, I set the discovery.zen.minimum_master_nodes to 2, and all the other settings are left to default (both nodes are master node, both nodes are data node, and both nodes are ingest).
In most of the blogs, I see that people come up with at least a three-node-cluster.
I have two question basically:
- Do I need to worry about the split-brain issue with my two-node cluster?
- How to configure the node related roles (master, data, ingest), when you have two nodes only?
