This document discusses Hadoop and related techno logies. It introduces Hadoop, its components MapReduce and HDFS, and how they work together. It also briefly mentions related Apache projects like Mahout and how companies like Amazon, Yahoo and Facebook use Hadoop in their systems. Finally, it covers Amazon's Elastic MapReduce service, which allows running Hadoop jobs in the cloud.
