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 the issue of how I…

Hadoop Streaming in F# and MapReduce (summary)

With all my recent posts around Hadoop Streaming I thought it would be useful to summarize them into a single post. The main objective of these posts was to put together a codebase to enable F# developers to write Map/Reduce libraries through a simple API. The full code posting can be found here: http://code.msdn.microsoft.com/Hadoop-Streaming-and-F-f2e76850 The…

As such I wanted to put together a sample that supports processing Office documents; more on support for PDF in a later post. As always the code can be downloaded from: http://code.msdn.microsoft.com/Hadoop-Streaming-and-F-f2e76850 Putting together this sample…
