Nodes not joining cluster in Elasticsearch 5.1 cluster

I want to setup a cluster with 3 nodes(1 master, 1 client and 1 data node) with Elasticsearch 5.1.1. I have connected 3 windows 10 machines through a wireless network and edited the elasticsearch.ymlfile of each node as follows:

master node:

cluster.name: searchapp

node.name: es-master-01
node.master: true
node.data: false
node.ingest: false

network.host: 192.168.1.3

discovery.zen.ping.unicast.hosts: ["es-client-01", "es-master-01",  "es-data-01"]

client node:

cluster.name: searchapp

node.name: es-client-01
node.master: false
node.data: false
node.ingest: true

network.host: 192.168.1.4

discovery.zen.ping.unicast.hosts: ["es-client-01", "es-master-01",  "es-data-01"]

data node:

cluster.name: searchapp

node.name: es-data-01
node.master: false
node.data: true
node.ingest: false

network.host: 192.168.1.2

discovery.zen.ping.unicast.hosts: ["es-client-01", "es-master-01",  "es-data-01"]

When I try to run elasticsearch on the master node it gives the following output enter image description here

The nodes are not joining the cluster and I tried replacing the hostnames to IPs but still the nodes aren't joining.

According to the attached logs, it seems that your elasticsearch cluster cannot resolve the host names for the machines.

I suggest to add all of your hosts names to the hosts file so each machine would know how to resolve the host names.

For linux:

/etc/hosts

For windows:

%SystemRoot%\System32\drivers\etc\hosts

Where by default, %SystemRoot% means: C:\Windows
