Hadoop SDK and Tutorials for Microsoft .NET Developers. Microsoft has begun to treat its developer community to a number of Hadoop-y releases related to its HDInsight (Hadoop in the cloud) service, and it’s worth rounding up the material.
It’s all Alpha and Preview so YMMV but looks like fun: Microsoft .NET SDK for Hadoop. This kit provides .NET API access to aspects of HDInsight including HDFS, HCatalag, Oozie and Ambari, and also some Powershell scripts for cluster management. Develop C# Hadoop streaming programs for HDInsight. Hadoop provides a streaming API to MapReduce that enables you to write map and reduce functions in languages other than Java. This tutorial walks you through an end-to-end scenario from developing/testing a Hadoop streaming MapReduce program using C# on an HDInsight emulator to running the MapReduce job on Windows Azure HDInsight and to retrieving the results. Prerequisites: Before you begin this tutorial, you must have the following: Install Windows Azure HDInsight Emulator. For instructions, see Get started using HDInsight Emulator.Install Windows Azure PowerShell on the emulator computer. In this article Develop a word count Hadoop streaming program in C# The word count solution contains two console application projects: mapper and reducer.
To create C# console application Open Visual Studio 2013.Click FILE, New, and then click Project.Type or select the following values: Click OK to create the project. Get started with the HDInsight Emulator. Discover more resources for these services: HDInsight This tutorial gets you started using the Microsoft HDInsight Emulator for Azure (formerly HDInsight Server Developer Preview).
The HDInsight Emulator comes with the same components from the Hadoop ecosystem as Azure HDInsight. For details, including information on the versions deployed, see What version of Hadoop is in Azure HDInsight?. HDInsight Emulator provides a local development environment for the Azure HDInsight. If you are familiar with Hadoop, you can get started with the Emulator using HDFS. The HDInsight Emulator can use only a single node deployment. Big Data University. Planet big data. Planet big data.
