Hive and XML File Processing

When I put together the “Generics based Framework for .Net Hadoop MapReduce Job Submission” code one of the goals was to support XML file processing. This was achieved by the creation of a modified Mahout document reader where one can specify the XML node to be presented for processing. But what if ones wants to…

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…
