What ports does Elasticsearch use for REST API?
By default, Elasticsearch exposes TCP port 9200 for REST API access and TCP port 9300 for internal cluster communication. Consider adding rules to allow connecting to TCP port 9200 from desired subnets, typically private subnets, and TCP port 9300 from the subnets where Elasticsearch nodes live.
What ports do Elasticsearch and Kibana listen on?
This bootstrap action configures Elasticsearch to listen on port 9200 and Kibana on port 80 on the master node of the cluster. By default these ports are protected from public access.

How do I access Elasticsearch cluster?
There are two ways to connect to your Elasticsearch cluster: Through the RESTful API or through the Java transport client. Both ways use an endpoint URL that includes a port, such as https://ec47fc4d2c53414e1307e85726d4b9bb.us-east-1.aws.found.io:9243 .

What is Logstash Elasticsearch?
Logstash is a light-weight, open-source, server-side data processing pipeline that allows you to collect data from a variety of sources, transform it on the fly, and send it to your desired destination. It is most often used as a data pipeline for Elasticsearch, an open-source analytics and search engine.
Ports for client applications
The WorkSpaces client application requires outbound access on the following ports:
Ports for Web Access
WorkSpaces Web Access requires outbound access for the following ports:
Domains and IP addresses to add to your allow list
For the WorkSpaces client application to be able to access the WorkSpaces service, you must add the following domains and IP addresses to the allow list on the network from which the client is trying to access the service.
Health check servers
The WorkSpaces client applications perform health checks over ports 4172 and 4195. These checks validate whether TCP or UDP traffic streams from the WorkSpaces servers to the client applications.
PCoIP gateway servers
WorkSpaces uses PCoIP to stream the desktop session to clients over port 4172. For its PCoIP gateway servers, WorkSpaces uses a small range of Amazon EC2 public IPv4 addresses. This enables you to set more finely grained firewall policies for devices that access WorkSpaces.
WSP gateway servers
Starting in June 2020, WorkSpaces streams the desktop session for WSP WorkSpaces to clients over port 4195 instead of port 4172. If you want to use WSP WorkSpaces, make sure that port 4195 is open to traffic.
Network interfaces
The primary network interface (eth1) provides connectivity to the resources within your VPC and on the internet, and is used to join the WorkSpace to the directory.
How does Elasticsearch work?
You can send data in the form of JSON documents to Elasticsearch using the API or ingestion tools such as Logstash and Amazon Kinesis Firehose. Elasticsearch automatically stores the original document and adds a searchable reference to the document in the cluster’s index. You can then search and retrieve the document using the Elasticsearch API.
Elasticsearch benefits
Elasticsearch offers simple REST based APIs, a simple HTTP interface, and uses schema-free JSON documents, making it easy to get started and quickly build applications for a variety of use-cases.
Getting started with Elasticsearch on AWS
Managing and scaling Elasticsearch can be difficult and requires expertise in Elasticsearch setup and configuration. To make it easy for customers to run open-source Elasticsearch, AWS offers Amazon OpenSearch Service to perform interactive log analytics, real-time application monitoring, website search, and more.
Getting Started with Elasticsearch and Kibana on Amazon EMR
September 8, 2021: Amazon Elasticsearch Service has been renamed to Amazon OpenSearch Service. See details.
What is Elasticsearch?
Elasticsearch is a distributed RESTful search and analytics engine built on top of Apache Lucene. Developed in Java and released as open source under Apache license, Elasticsearch can index large volumes of log files and text content in real-time and allows users to query them in free form text using RESTful apis.
What is Kibana?
Kibana is a web interface for Elasticsearch and provides visualization capabilities on top of the content indexed on an Elasticsearch cluster. You can create bar, line and scatter plots, or pie charts and maps on top of large volumes of data. You can also do comparisons of queries across different time ranges.
Installing Elasticsearch and Kibana on Amazon EMR
First, install the EMR CLI tools. Next, install Elasticsearch and Kibana on Amazon EMR by using Amazon EMR’s bootstrap action feature. A bootstrap action script allows you to customize existing applications or install additional software when launching a new cluster.
Verifying the installation
Once the cluster is up and running, you can SSH into the master node and perform following tests to verify the installation.
Using Kibana
Since this bootstrap action configures Kibana to listen at port 80 on the master node, you can point the browser to the Master Node DNS public address (example: http://ec2-54-77-165-138.eu-west-1.compute.amazonaws.com) and get the Kibana console running.
Conclusion
This post has shown you how Amazon EMR lets you install and configure additional software (in this case Elasticsearch and Kibana) on top of Hadoop. Amazon EMR maintains an open source repository for bootstrap actions. Take a look and see if there is already a bootstrap action that interests you.
How does Elasticsearch work?
Each Elasticsearch node has two different network interfaces. Clients send requests to Elasticsearch’s REST APIs using its HTTP interface, but nodes communicate with other nodes using the transport interface. The transport interface is also used for communication with remote clusters, and by the deprecated Java transport client.
How many publish addresses does Elasticsearch have?
Each Elasticsearch node has an address at which clients and other nodes can contact it, known as its publish address. Each node has one publish address for its HTTP interface and one for its transport interface. These two addresses can be anything, and don’t need to be addresses of the network interfaces on the host.
What are the requirements for a node to be accessible?
The only requirements are that each node must be: Accessible at its transport publish address by all other nodes in its cluster, and by any remote clusters that will discover it using Sniff mode . Accessible at its HTTP publish address by all clients that will discover it using sniffing.
Can elasticsearch bind to more than one address?
Elasticsearch can bind to more than one address if needed, but most nodes only bind to a single address. Elasticsearch can only bind to an address if it is running on a host that has a network interface with that address. If necessary, you can configure the transport and HTTP interfaces to bind to different addresses.
Can you expose an unprotected node to the public internet?
Never expose an unprotected node to the public internet. If you do, you are permitting anyone in the world to download, modify, or delete any of the data in your cluster.
Does ElasticSearch compress response?
The compression settings do not configure compression for responses. Elasticsearch will compress a response if the inbound request was compressed—even when compression is not enabled. Similarly, Elasticsearch will not compress a response if the inbound request was uncompressed—even when compression is enabled.
