I am trying to setup ES cluster( 3 node) on EC2. I have tried lot of configs but ended with this config: ``` > cluster.name: ES-CLUSTER > node.name: ES-NODE-01 > node.max_local_storage_nodes: 1 > node.rack_id: rack_us_east_1d > index.number_of_shards: 16 > index.number_of_replicas: 1 > gateway.recover_after_nodes: 3 > gateway.recover_after_time: 2m > gateway.expected_nodes: 3 > discovery.zen.minimum_master_nodes: 3 > discovery.zen.ping.multicast.enabled: false > cloud.aws.access_key: ******** > cloud.aws.secret_key: ****** > cloud.aws.region: us-east-1 > discovery.type: ec2 > discovery.ec2.groups: groups-name > plugin.mandatory: cloud-aws,analysis-icu,analysis-phonetic > http.cors.enabled: true > http.cors.allow-origin: "*" > network.host: _ec2:privateIpv4_ > network.bind_host: 0.0.0.0 > network.publish_host: _ec2:privateIpv4_ ``` Now it is working. I am not sure it is right setting or not ? Can anybody guide me what is right way t do this ? Thanks ---

And also be aware that you won't be able to define `index.number_of_shards` in `elasticsearch.yml` in 5.0. You should use an index template for that. ---

While we are at it, it's Elasticsearch, not ElasticSearch. That's definitely a best practise 😉 ---

What are the recommended number for number\_of\_shards ? Our use case are 20 parallel requests where each request average 10k documents. @warkolm Ok, Next time I would follow it. ---

You mean you are bulk indexing these? ---
