Hadoop at Yahoo!

Introduction

Apache Hadoop* is an open source Java framework for processing and querying vast amounts of data on large clusters of commodity hardware. Hadoop is a top level Apache project, initiated and led by Yahoo!. It relies on an active community of contributors from all over the world for its success.

With a significant technology investment by Yahoo!, Apache Hadoop has become an enterprise-ready cloud computing technology. It is becoming the industry de facto framework for big data processing.

The Hadoop project is an integral part of the Yahoo! cloud infrastructure — and is the heart of many of Yahoo!’s important business processes.

We run the world's largest Hadoop clusters, work with academic institutions and other large corporations on advanced cloud computing research and our engineers are leading participants in the Hadoop community.

Yahoo! sponsors the Annual Hadoop Summit and the monthly Hadoop User Group.
