I am using elastic-7.6.1. I am trying to setup elastic cluster locally in vm with two masters and one slave. I have downloaded tar file and extracted into 3 different locations and modified the elasticsearch.yml with the below configurations. first configuration ``` cluster.name: test-cluster node.name: m1node node.master: true node.data: true network.host: xx.xxx.xxx.xx http.port: 9200 transport.tcp.port: 9300 discovery.seed_hosts: - xx.xxx.xxx.xx:9202 - xx.xxx.xxx.xx:9200 - 1xx.xxx.xxx.xx:9201 cluster.initial_master_nodes: - xx.xxx.xxx.xx:9200 - xx.xxx.xxx.xx:9201 ``` second configuration ``` cluster.name: test-cluster node.name: m2node node.master: true node.data: true network.host: xx.xxx.xxx.xx http.port: 9201 transport.tcp.port: 9301 discovery.seed_hosts: - xx.xxx.xxx.xx:9202 - xx.xxx.xxx.xx:9200 - xx.xxx.xxx.xx:9201 cluster.initial_master_nodes: - xx.xxx.xxx.xx:9200 - xx.xxx.xxx.xx:9201 ``` third configuration ``` cluster.name: test-cluster node.name: s1node node.master: false node.data: true network.host: xx.xxx.xxx.xx transport.tcp.port: 9302 http.port: 9202 discovery.seed_hosts: - xx.xxx.xxx.xx:9202 - xx.xxx.xxx.xx:9200 - xx.xxx.xxx.xx:9201 cluster.initial_master_nodes: - xx.xxx.xxx.xx:9200 - xx.xxx.xxx.xx:9201 ``` I started the three elastic search instances using ./elasticsearch. The server starts but it doesn't discover other nodes.I get this error. ``` [2020-03-16T08:08:11,542][WARN][o.e.c.c.ClusterFormationFailureHelper] [s1node] master not discovered yet: have discovered

Hey, first there is no such thing as a slave node. The `node.master` setting is only about being master eligible. Second, you are trying to connect to the HTTP ports of your nodes, instead of using the node-to-node port, which is `9300`. This is also why you are getting an error like `received HTTP response on transport port, ensure that transport port (not HTTP port) of a remote node is specified in the configuration` which tries to hint at the fact, that there seems to be a mixup between HTTP and node-to-node communication. --Alex ---
