Hadoop is a Java-based programming framework that supports the processing and storage of extremely large datasets on a cluster of inexpensive machines. Hadoop clusters are relatively complex to set up, so the project includes a stand-alone mode which is suitable for learning about Hadoop, performing simple operations, and debugging. In this tutorial, you’ll install Hadoop in stand-alone mode and run and included MapReduce example programs to verify the installation. Choose your operating system below to get started.
