  • Blog Post: Framework for .Net Hadoop MapReduce Job Submission Binary Output

    To end the week I decided to make a minor change to the “ Generics based Framework for .Net Hadoop MapReduce Job Submission ”. I have been doing some work on creating a co-occurrence matrix for item recommendations. I was going to map the process to a MapReduce job(s), then came across...

  • Blog Post: Hadoop Streaming and Reporting

    If like me you are a .Net developer and have written some Streaming jobs it is not immediately obvious how one can do any reporting.
