Do the following changes Steps to install Elastic SearchExample Elasticsearch.yml and update the following parameters:

...

cluster.name: zephyr
node.name: "Node1"
node.master: true
node.data: true
script.inline: true
script.stored: true
network.bind_host: 192.168.45.21
network.publish_host: 192.168.45.21
network.host: 192.168.45.21
transport.tcp.port: 9300
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.45.21:9300"]
indices.query.bool.max_clause_count: 9012

Sample elasticsearch.yml file attached : Steps to install Elastic SearchExample Elasticsearch.yml

Changes need to do in Zephyr

1. In Jdbc properties need to change
   

   #transport|node
   transport.nodes=192.168.45.21:9300, 192.168.45.22:9300

ElasticSearch Cluster

• Elastic Search in cluster should be in Odd Number minimum node to be in elastic search cluster should be 3 node
• Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
  
  

...

discovery.zen.ping.unicast.hosts should contain all the elasticsearch system's host ip and port which are in cluster.

Sample elasticsearch.yml file attached :

If elastic Search is in Cluster then in ZE we have to change the "number_of_shards" and "number_of_replicas"

Navigate to the ZE installation Dir 

C:\Program Files\Zephyr\tomcat\webapps\flex\WEB-INF\template\zephyr

In this file _settings.json

change the number of shards and number of replicas

...

1. In Jdbc properties need to change
   

   #transport|node
   transport.nodes=192.168.11.144:9300,192.168.11.145:9300.192.168.11.146:9300
