 # Create Linux-based clusters in HDInsight using the .NET SDK

 Learn how to create an [Apache Hadoop](https://hadoop.apache.org/) cluster in Azure HDInsight cluster using the .NET SDK.
 
 > [!IMPORTANT]  
 > The steps in this document create a cluster with one worker node. If you plan on more than 32 worker nodes, either at cluster creation or by scaling the cluster after creation, you need to select a head node size with at least 8 cores and 14GB ram.
