Hello, I am trying to form a 3 node ES cluster but i am getting a above mentioned error. I have one master node and 2 data nodes. My ES configurations are as follows: ``` **For master node:** cluster.name: InTouch cluster.remote.connect: false network.host: ServerA transport.host: ServerA transport.tcp.port: 9300-9400 node.name: Master-node node.master: true node.data: false node.ingest: true discovery.zen.ping.unicast.hosts: [ServerA, ServerB,ServerC] cluster.initial_master_nodes: ["Master-node","Data-node1"] discovery.zen.minimum_master_nodes: 2 bootstrap.memory_lock: true network.bind_host: *local* path.data: /elasticsearch/data/ path.logs: /var/log/elasticsearch/ path.repo: /elasticsearch/repo/ **For Data node 1** : cluster.name: InTouch node.name: Data-node1 node.master: true node.data: true node.ingest: false network.host: ServerB discovery.zen.ping.unicast.hosts: [ServerA, ServerB,ServerC] transport.tcp.port: 9300-9400 path.data: /elasticsearch/data/ path.logs: /var/log/elasticsearch/ path.repo: /elasticsearch/repo/ **For Data node 2** : cluster.name: InTouch node.name: Data-node2 node.master: false node.data: true network.host: ServerC discovery.zen.ping.unicast.hosts: [ServerA, ServerB,ServerC] transport.tcp.port: 9300-9400 path.data: /elasticsearch/data/ path.logs: /var/log/elasticsearch/ path.repo: /elasticsearch/repo/ ``` Thanks, Priyanka ---

So `Master-node` is looking in vain for a node with ID `Y11KbKB-SX2HIYM77Z1Zqg`. It is not discovering any other nodes. I suspect that `Y11KbKB-SX2HIYM77Z1Zqg` is the node ID of `Data-node1`. Check the first few log lines on `Data-node1` to find its node ID to confirm or otherwise. I recommend fixing the port of your master-eligible nodes using `transport.tcp.port: 9300`. This means both `Master-node` and `Data-node1`. You are currently using `9300-9400` but if Elasticsearch picks a port other than `9300` then you need to configure `discovery.zen.ping.unicast.hosts` with that port instead. Note also that in v7 you should replace `discovery.zen.ping.unicast.hosts` with `discovery.seed_hosts`, and `discovery.zen.minimum_master_nodes` should be removed. Note also that there's no point in having two master-eligible nodes. I recommend setting `node.master: true` on all three nodes. ---

Hello @DavidTurner, ID `Y11KbKB-SX2HIYM77Z1Zqg` is of `data node 3`. I have checked the logs for the same. I have changed `transport.tcp.port: 9300-9400` settings to only `9300` port. I have also repplaced `discovery.zen.ping.unicast.hosts` with `discovery.seed_hosts` I have also changed the setting for `node.master: true` for all the 3 nodes. I am getting below message after run of all the 3 nodes on master node: ``` [2020-01-06T12:45:41,576][INFO][o.e.x.m.e.l.LocalExporter] [Master-node] waiting for elected master node [{Data-node2}{Y11KbKB-SX2HIYM77Z1Zqg}{UrZFy5cOQ7Ck3dBs3HEH0Q}{server C}{ip_address of server B:9300}{dlm}{ml.machine_memory=17179267072, ml.max_open_jobs=20, xpack.installed=true}] to setup local exporter[default_local] (does it have x-pack installed?)

Hello @DavidTurner, Thanks for update. I have one more question. All 3 nodes are master eligible. So if one goes down other should be eligible to elect itself as a master node and will form a 2 node cluster. How i can check this with my cluster? Can you please guide me on this more? Regards, Priyanka ---
