Title : Hadoop Explained
Edition : 
Year : 2014
Authors : Aravind Shenoy
Publisher : Packt

 Preface
With the almost unfathomable increase in web traffic over recent years, driven by millions of connected users, businesses are gaining access to massive amounts of complex, unstructured data from which to gain insight. When Hadoop was introduced by Yahoo in 2007, it brought with it a paradigm shift in how this data was stored and analyzed. Hadoop allowed small- and medium-sized companies to store huge amounts of data on cheap commodity servers in racks. This data could thus be processed and used to make business decisions that were supported by ‘Big Data’. Hadoop is now implemented in major organizations such as Amazon, IBM, Cloudera, and Dell to name a few. This book introduces you to Hadoop and to concepts such as MapReduce, Rack Awareness, YARN, and HDFS Federation, which will help you get acquainted with the technology.
