Hadoop history
*The genesis of Hadoop came from the Google File System paper[11] that was published in October 2003. This paper spawned another research paper from Google – MapReduce: Simplified Data Processing on Large Clusters.[12] Development started on the Apache Nutch project, but was moved to the new Hadoop subproject in January 2006.[13] Doug Cutting, who was working at Yahoo! at the time,[14] named it after his son's toy elephant.[15] The initial code that was factored out of Nutch consisted of 5k lines of code for HDFS and 6k lines of code for MapReduce. The first committer added to the Hadoop project was Owen O’Malley in March 2006.[16] Hadoop 0.1.0 was released in April 2006[17] and continues to evolve by the many contributors[18] to the Apache Hadoop project.
