 # Use C# with MapReduce streaming on Apache Hadoop in HDInsight
 
 Learn how to use C# to create a MapReduce solution on HDInsight.
 
-Apache Hadoop streaming is a utility that allows you to run MapReduce jobs using a script or executable. In this example, .NET is used to implement the mapper and reducer for a word count solution.
