Get started with a Hadoop sandbox, an emulator on a virtual machine
Learn how to install the Hadoop sandbox from Hortonworks on a virtual machine to learn about the Hadoop ecosystem. The sandbox provides a local development environment to learn about Hadoop, Hadoop Distributed File System (HDFS), and job submission. Once you are familiar with Hadoop, you can start using Hadoop on Azure by creating an HDInsight cluster. For more information on how to get started, see Get started with Hadoop on HDInsight.
