Scaling Big Data with Hadoop and Solr

By: Hrishikesh Vijay Karambelkar

Overview of this book

<p>As data grows exponentially day-by-day, extracting information becomes a tedious activity in itself. Technologies like Hadoop are trying to address some of the concerns, while Solr provides high-speed faceted search. Bringing these two technologies together is helping organizations resolve the problem of information extraction from Big Data by providing excellent distributed faceted search capabilities.</p> <p>Scaling Big Data with Hadoop and Solr is a step-by-step guide that helps you build high performance enterprise search engines while scaling data. Starting with the basics of Apache Hadoop and Solr, this book then dives into advanced topics of optimizing search with some interesting real-world use cases and sample Java code.</p> <p>Scaling Big Data with Hadoop and Solr starts by teaching you the basics of Big Data technologies including Hadoop and its ecosystem and Apache Solr. It explains the different approaches of scaling Big Data with Hadoop and Solr, with discussion regarding the applicability, benefits, and drawbacks of each approach. It then walks readers through how sharding and indexing can be performed on Big Data followed by the performance optimization of Big Data search. Finally, it covers some real-world use cases for Big Data scaling.</p> <p>With this book, you will learn everything you need to know to build a distributed enterprise search platform as well as how to optimize this search to a greater extent resulting in maximum utilization of available resources.</p>

Lily – running Solr and Hadoop together


Lily is an open source distributed application by NGDATA that brings in together the capabilities of Apache Hadoop, HBase, ZooKeeper, and Solr together to allow end user applications (web portals, content management systems, and so on) to enable enterprise-wide access to its distributed search through standard interfaces.

The architecture

Lily provides scalability and replication through its distributed architecture. Lily has multiple nodes; each node is responsible for participating in one or more of the functionalities. Primarily, Lily is designed to work as a content management system. The storage is Apache HBase which is running on top of the Hadoop framework, and the query/search mechanism is based on Apache Solr. Lily exposes complete functionality of Apache Solr on top of its record base. Lily provides functional layering, scalability, and fault tolerance on top of these. Lily provides basic record management, with support for open standards such...
