Windows Azure HDInsight Service is a service that deploys and provisions Apache™ Hadoop™ clusters in the cloud, providing a software framework designed to manage, analyze and report on big data. The HDInsight Service for Windows Azure makes Apache Hadoop available as a service in the cloud. It makes the HDFS/MapReduce software framework and related projects such as Pig and Hive available in a simpler, more scalable, and cost efficient environment. The main conceptual documentation that outlines how to get started with the Windows Azure HDInsight Service is available at Windows Azure HDInsight Documentation.
Windows Azure HDInsight PowerShell
The HDInsight Service uses Windows Azure PowerShell to configure, run, and post-process Hadoop jobs. The documentation for the cmdlets is available at HDInsight Cmdlet Reference Documentation.
Windows Azure HDInsight .NET SDK
The HDInsight Service has a .NET SDK that provides classes related the creation, configuration, submission, and monitoring of to Hadoop jobs managed by a Windows Azure HDInsight Service. It also provides classes used to manage Windows Azure subscriptions using the HDInsight Service and to configure the clusters, storage accounts, MapReduce programs, and the Hive and Oozie components associated with the HDInsight clusters managed by a Windows Azure subscription. The documentation for the .NET SDK is available at HDInsight SDK Reference Documentation.
