Session

Introduction to Hadoop

Doug Cutting, Yahoo!

Date: Wednesday, March 28
Time: 3:25pm - 3:50pm
Location: Douglas B

Hadoop is an open source framework for running applications on large clusters of commodity hardware. The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named MapReduce, where the application is divided into many small fragments of work, each of which may be executed or reexecuted on any node in the cluster. In addition, it provides a distributed file system (HDFS) that stores data on the compute nodes, providing very high aggregate bandwidth across the cluster. Both MapReduce and the distributed file system are designed so that node failures are automatically handled by the framework.
