Hi guys, I downloaded the ElasticSearch zip for Windows, I extrated it and made three copies of the folder. Then I configured in every folder the elasticsearch.yml. cluster.name: elasticsearch-dev node.name: masterNode1 node.master: true network.host: 127.0.0.1 http.port: 9201 discovery.zen.ping.unicast.hosts: ["127.0.0.1::9202","127.0.0.1::9203"] discovery.zen.minimum\_master\_nodes: 3 cluster.name: elasticsearch-dev node.name: masterNode2 node.master: true network.host: 127.0.0.2 http.port: 9202 discovery.zen.ping.unicast.hosts: ["127.0.0.1::9201","127.0.0.1::9203"] discovery.zen.minimum\_master\_nodes: 3 cluster.name: elasticsearch-dev node.name: masterNode3 node.master: true network.host: 127.0.0.3 http.port: 9203 discovery.zen.ping.unicast.hosts: ["127.0.0.1::9201","127.0.0.1::9202"] discovery.zen.minimum\_master\_nodes: 3 Then I started the bin/elasticsearch.bat file. I get in every console window the message: failed to resolve host [127.0.0.x] x = 1, 2 or 3 What is wrong in my configuration? Kind regards ---

Elasticsearch internally uses the transport protocol for communication, so you need to specify the transport port, e.g. 9300, 9301, 9302, for `discovery.zen.ping.unicast.hosts`. ---

I did this: discovery.zen.ping.unicast.hosts: ["127.0.0.1::9201","127.0.0.1::9202"] is something wrong with the configuration? ---

Yes. As Christian said, the port are 9300, 9301, ... ---

Got it. I changed the configuration. But it's still not working. I get the message: failed to resolve hot [127.0.0.1::9301] then the process stopps: not enough master nodes discovered during pinging.

But this did not work. ---

Thank you for your support. It's still not working. To identify the problem I started just one instance of elasticsearch. It got the following exception ``` X:\Analytics\elastic\elasticsearch cluster\elasticsearch-dev-3\masterNode-1\bin>elasticsearch [2018-03-05T18:10:02,981][INFO][o.e.n.Node] [masterNode1] initializing ... ...

PS: I have no other service running. I don't understand why the address is already in use. I checked with resmon if the port is in use by another application. Its not. It's free. PSS: I have another copy of Elasticsearch, its just a single node. I configured it to use the port 9300. I got the same exception that I pasted above. ---

As it looks like you are trying to set up the 3 nodes on a single host, try the following config: ```auto cluster.name: elasticsearch-dev node.name: masterNode1 node.master: true network.host: 127.0.0.1 http.port: 9200 discovery.zen.ping.unicast.hosts: ["127.0.0.1::9300","127.0.0.1::9301","127.0.0.1::9302"] discovery.zen.minimum_master_nodes: 2 cluster.name: elasticsearch-dev node.name: masterNode2 node.master: true network.host: 127.0.0.1 http.port: 9201 discovery.zen.ping.unicast.hosts: ["127.0.0.1::9300","127.0.0.1::9301","127.0.0.1::9302"] discovery.zen.minimum_master_nodes: 2 cluster.name: elasticsearch-dev node.name: masterNode3 node.master: true network.host: 127.0.0.1 http.port: 9202 discovery.zen.ping.unicast.hosts: ["127.0.0.1::9300","127.0.0.1::9301","127.0.0.1::9302"] discovery.zen.minimum_master_nodes: 2 ``` ---
