This cluster will consist of 3 data nodes, so with this scenario a master node will be elected and with a 3 node cluster, we would want toavoidasplit brainand havequorumof master-eligible nodes. In a future post, I will be going through how to setup aElasticsearch Cluster with Dedicated...
ElasticSearch has become a public company now, having made an IPO and sold shares. One of its first actions was to create ElasticSearch version 7. Unfortunately the installation instructions for how to set up a cluster with version have changed. So we have written new instructions. The main di...
