One node not joining a cluster - 5.6.4

Elastic Stack Elasticsearch
1

Hello all,

i have the following situation, 3 Elasticsearch nodes in the same server, with IP adresses 10.20.30.1, 10.20.30.2, 10.20.30.3 but one of these nodes doesn't join the cluster, it's not even a specific one.

Here is the elasticsearch.yml important configs of each node:

Node 1:

 network.host: 10.20.30.1
 http.port: 9200
 discovery.zen.ping.unicast.hosts: ["10.20.30.2", "10.20.30.3"]
 discovery.zen.minimum_master_nodes: 2
 indices.query.bool.max_clause_count : 10000
 node.attr.tipono: hot
 node.master : true
 node.data : true
 node.ingest : false

Node 2:

 network.host: 10.20.30.2
 http.port: 9200
 discovery.zen.ping.unicast.hosts: ["10.20.30.1", "10.20.30.3"]
 discovery.zen.minimum_master_nodes: 2

Node 3:

network.host: 10.20.30.3
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.20.30.1", "10.20.30.2"]
discovery.zen.minimum_master_nodes: 2

This is the result of a curl to each node:

Node 1:

{
  "name" : "Node1",
  "cluster_name" : "ClusterNode",
  "cluster_uuid" : "e3Oc6WnLRtCpAHh2V3DdFA",
  "version" : {
  "number" : "5.6.4",
  "build_hash" : "8bbedf5",
  "build_date" : "2017-10-31T18:55:38.105Z",
  "build_snapshot" : false,
  "lucene_version" : "6.6.1"
},
 "tagline" : "You Know, for Search"
}

Node 2:

{
  "name" : "Node2",
  "cluster_name" : "ClusterNode",
  "cluster_uuid" : "e3Oc6WnLRtCpAHh2V3DdFA",
  "version" : {
  "number" : "5.6.4",
  "build_hash" : "8bbedf5",
  "build_date" : "2017-10-31T18:55:38.105Z",
  "build_snapshot" : false,
  "lucene_version" : "6.6.1"
},
  "tagline" : "You Know, for Search"
}

Node 3:

{
  "name" : "Node3",
  "cluster_name" : "ClusterNode",
  "cluster_uuid" : "_na_",
  "version" : {
  "number" : "5.6.4",
  "build_hash" : "8bbedf5",
  "build_date" : "2017-10-31T18:55:38.105Z",
  "build_snapshot" : false,
  "lucene_version" : "6.6.1"
},
  "tagline" : "You Know, for Search"
}

is there any config that must be done on the elasticsearch.yml that im missing?

Any help is welcome !

Hi @DanV,

Can you please share the logs of the node which is not joining the cluster?
