Hi Team,  
Here is my task wherein add new node to exisiting es cluster.  
Followed below steps ;;

1. Add instance where in es\_java\_heap\_size\_gb: 20
2. Added es and restarted .PFA text file for elasticsearch.yml  
When I run checks ::  
curl GET [http://localhost:9200/\_nodes/stats?pretty](http://localhost:9200/_nodes/stats?pretty)  
curl: (6) Could not resolve host: GET; Unknown error  
{  
"\_nodes" : {  
"total" : 1,  
"successful" : 1,  
"failed" : 0  
},  
"cluster\_name" : "test",  
"nodes" : {  
"node1" : {  
"timestamp" : 1607180640596,  
ITs not displaying another node

```
curl -X GET http://localhost:9200/_cat/nodes?pretty

<nodeIP> 17 8 0 0.03 0.13 0.13 dilmrt * <node1>

```

Tried below Option ::  
Tried disabling firewall .It dint wrk

**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](https://www.elastic.co/guide/en/elasticsearch/reference/index.html)

# 

# ---------------------------------- Cluster -----------------------------------

# 

# Use a descriptive name for your cluster:

# 

cluster.name: xxx

# 

# ------------------------------------ Node ------------------------------------

# 

# Use a descriptive name for the node:

# 

node.name: x.x.x

# 

# 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: /elasticsearch/elasticsearch  
#path.data: /es\_data/elasticsearch

# 

# Path to log files:

# 

path.logs: /var/log/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 -----------------------------------

# 

# Set the bind address to a specific IP (IPv4 or IPv6):

# 

network.host: ["0.0.0.0"]

# 

"/etc/elasticsearch/elasticsearch.yml" 90L, 3029C

# Set a custom port for HTTP:

# 

#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]"]

# 

# 

# Bootstrap the cluster using an initial set of master-eligible nodes:

# 

cluster.initial\_master\_nodes: ["xxx","xx"]

# 

# For more information, consult the discovery and cluster formation module documentation.

# 

# ---------------------------------- Gateway -----------------------------------

# 

# Block initial recovery after a full cluster restart until N nodes are started:

# 

#gateway.recover\_after\_nodes: 3

# 

# For more information, consult the gateway module documentation.

# 

# ---------------------------------- Various -----------------------------------

# 

# Require explicit names when deleting indices:

# 

#action.destructive\_requires\_name: true  
indices.memory.index\_buffer\_size: 20%  
discovery.seed\_hosts: ["node1", "node2"]

Please format your code/logs/config using the `</>` button, or markdown style back ticks. It helps to make things easy to read which helps us help you 🙂
