Elasticsearch 8.x Cookbook - Fifth Edition

By: Alberto Paro

Overview of this book

Elasticsearch is a Lucene-based distributed search engine at the heart of the Elastic Stack that allows you to index and search unstructured content with petabytes of data. With this updated fifth edition, you'll cover comprehensive recipes relating to what's new in Elasticsearch 8.x and see how to create and run complex queries and analytics. The recipes will guide you through performing index mapping, aggregation, working with queries, and scripting using Elasticsearch. You'll focus on numerous solutions and quick techniques for performing both common and uncommon tasks such as deploying Elasticsearch nodes, using the ingest module, working with X-Pack, and creating different visualizations. As you advance, you'll learn how to manage various clusters, restore data, and install Kibana to monitor a cluster and extend it using a variety of plugins. Furthermore, you'll understand how to integrate your Java, Scala, Python, and big data applications such as Apache Spark and Pig with Elasticsearch and create efficient data applications powered by enhanced functionalities and custom plugins. By the end of this Elasticsearch cookbook, you'll have gained in-depth knowledge of implementing the Elasticsearch architecture and be able to manage, search, and store data efficiently and effectively using Elasticsearch.

Removing a plugin

You have installed some plugins, and now you need to remove a plugin because it's not required. Removing an Elasticsearch plugin is easy if everything goes right, otherwise, you will need to remove it manually.

Before removing a plugin, it is safer to stop the Elasticsearch server to prevent errors due to the deletion of a plugin JAR file.

How to do it…

The steps to remove a plugin are as follows:

  1. Stop your running node to prevent exceptions that are caused due to the removal of a file.
  2. Use the Elasticsearch plugin manager, which comes with its script wrapper (bin/elasticsearch-plugin).

On Linux and macOS X, type the following command:
