Owen has been contributing patches to Hadoop since before it became an independent Apache project. He was the first committer added and still remains one of the most active contributors to Apache Hadoop. Prior to co-founding Hortonworks, Owen worked on Yahoo! Search’s WebMap project, which built a graph of the known web and applied many heuristics to the entire graph. Once ported to Apache Hadoop, it became the single largest known Hadoop application. He has a PhD in Software Engineering from the University of California, Irvine.
