Need Help to Create Cluster with 2 Dedicated Master Node and 3 Data Node

Hi,
I have a total 5 Instances in Production and I am trying to create below
1: - 2 Dedicated Master Node ( Will be accessible from Http URL in browser as well to see the Stats
2: - 1 Master + Data ( to avoid Brin Split )
3 : - 2 Dedicated Data Node

below is My Master Node setting

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: ES-CLUSTER
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: NODE-SM01
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /u01/data/elasticsearch
#
# Path to log files:
#
path.logs: /u01/logs/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 10.0.6.61,
node.roles: [ master ]
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
discovery.seed_hosts: ['10.0.6.61', '10.0.6.62', '10.0.6.63']
# Bootstrap the cluster using an initial set of master-eligible nodes:
#i
cluster.initial_master_nodes: ['10.0.6.61', '10.0.6.62', '10.0.6.63']
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false

will it be fine,
I need the setting for Point # 2 which I mention above
can anyone help with this

Hi,

For the node that will act as both a master and data node (Point #2), you can use a similar configuration, but you need to include data in the node.roles setting. Here's an example:

node.name: NODE-MD01
network.host: 10.0.6.63
node.roles: [ master, data ]
discovery.seed_hosts: ['10.0.6.61', '10.0.6.62', '10.0.6.63']
cluster.initial_master_nodes: ['10.0.6.61', '10.0.6.62', '10.0.6.63']
