How many nodes are in Elasticsearch cluster?
Instead, it would simply have to wait until it rejoined the cluster. The formula for determining the value to use is: N / 2 + 1 , where N is the total number of nodes in your cluster. If you really want to only use two nodes, you can still prevent split-brain by using another Elasticsearch config setting, node. data .
