Apache Hadoop Cookbook

Apache Hadoop is an open-source software framework written in Java for distributed storage and distributed processing of very large data sets on computer clusters built from commodity hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common and should be automatically handled by the framework. Hadoop has become the de-facto tool used for Distributed computing. For this reason we have provided an abundance of tutorials here at Java Code Geeks, most of which can be found here. In this ebook, we provide a compilation of Hadoop based examples that will help you kick-start your own web projects. We cover a wide range of topics, from installation and configuration, to distributed caching and streaming.

 
 

Amazon S3 Tutorial

Amazon S3 (Simple Storage Service) is a web service offered by Amazon Web Services. Amazon S3 provides storage through web services interfaces (REST, SOAP, and BitTorrent). Amazon does not make details of S3’s design public, though it clearly manages data with an object storage architecture. According to Amazon, S3’s design aims to provide scalability, high availability, and low latency at commodity costs. S3 is designed to provide 99.999999999% durability and 99.99% availability of objects over a given year, though there is no service-level agreement for durability. In this ebook, we provide a comprehensive guide so that you can develop your own Amazon S3 based applications. We cover a wide range of topics, from setup and configuration, to API usage and pricing.

Elasticsearch Tutorial
Elasticsearch is a search engine based on Lucene. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch is developed in Java and is released as open source under the terms of the Apache License. Elasticsearch is the most popular enterprise search engine followed by Apache Solr, also based on Lucene.Elasticsearch can be used to search all kinds of documents. It provides scalable search, has near real-time search, and supports multitenancy. Elasticsearch is distributed, which means that indices can be divided into shards and each shard can have zero or more replicas. Each node hosts one or more shards, and acts as a coordinator to delegate operations to the correct shard(s).
