Before jumping into Apache Hadoop, Read about BigData. click here So let's Talk about the History of Apache Hadoop Hadoop was created by Doug Cutting and Mike Cafarella in 2005.  It was originally developed to support distribution for the Nutch search engine project.  Doug, who was working at Yahoo! at the time and is now Chief Architect of Cloudera, named the project after his son's toy elephant.  Cutting's son was 2 years old at the time and just beginning to talk.  He called his beloved stuffed yellow elephant "Hadoop".

Big Data is the huge amount of data which can't be stored and processed using the traditional methods within the given time frame. So, The Question arises that how much big should be the big data . Generally, people think that the data whose size is more than GB, TB, PB is big data. But, it's not the case. some data which is small in size can be a big data.

Some analysis of data in the real world Facebook-100TB /day twitter- 4400 twites /day LinkedIn - 10TB/day Google+ - 10TB/...
