Hadoop Explained

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.
