ES 5.5 "Failed to send join request to master" :: AWS EC2 instance

Elastic Stack Elasticsearch
1

Hi.

It's first time that work with ES with Cluster and AWS EC2 instances.

  • I'm working with ES 5.5.1 on instancd with Ubuntu 16.04
  • All nodes are up and running
  • All nodes has a Security Group with permissions for all traffic between nodes (all ports)
  • Internal firewall on very machine white list for every node

Master elasticsearch,yml

cluster.name: excelle
node.name: ${HOSTNAME}
node.master: true
path.data: /srv/data
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 172.31.44.107
discovery.zen.ping.unicast.hosts: ["172.31.44.107", "172.31.2.148", "172.31.18.76"]

node02 elasticsearch,yml

cluster.name: excelle
node.name: ${HOSTNAME}
node.master: false
path.data: /srv/data
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 172.31.18.76
discovery.zen.ping.unicast.hosts: ["172.31.44.107", "172.31.2.148", "172.31.18.76"]

node02 elasticsearch,yml

cluster.name: excelle
node.name: ${HOSTNAME}
node.master: false
path.data: /srv/data
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 172.31.2.148
