It gives me great pleasure to introduce a new contributor to DataTechBlog.  Ms. Neha Sharma makes her debut with this blog post.  Neha is a talented software engineer and big data enthusiast.  In this post, she will be demonstrating how to enhance the “word count” map reduce job that ships with hadoop.   The enhancements will include the removal of “stop” words, the option for case insensitivity and the removal of punctuation.
