Welcome to Hadoop!


Hadoop Introduction

The Apache Hadoop project develops open-source software for reliable, scalable, distributed computing, including:

  • Hadoop Core, our flagship sub-project, provides a distributed filesystem (HDFS) and support for the MapReduce distributed computing metaphor.
  • HBase builds on Hadoop Core to provide a scalable, distributed database.
  • Pig is a high-level data-flow language and execution framework for parallel computation. It is built on top of Hadoop Core.
  • ZooKeeper is a highly available and reliable coordination system. Distributed applications use ZooKeeper to store and mediate updates for critical shared state.
  • Hive is a data warehouse infrastructure built on Hadoop Core that provides data summarization, adhoc querying and analysis of datasets.
