Running Hadoop on a Raspberry Pi 2 cluster ZDNet

I've been involved with cluster computing ever since DEC introduced VAXcluster in 1984. Today you can build a much more powerful cluster for under $1,000, including much more storage than anyone could afford back then. Hadoop is the open-source version of Google's Map/Reduce and Google File System (GFS), widely used for large data-crunching applications. It is a shared-nothing cluster, which means that as you add cluster nodes, performance scales up smoothly. Raspberry Pi: Hands-on with the Pi-Desktop kit Raspberry Pi's smaller, cheaper rival: NanoPi Neo Plus2 weighs in at $25 This is why you need to learn the Raspberry Pi 3 (ZDNet Academy) Building a 300 node Raspberry Pi supercomputer Raspberry Pi: Google plans more AI projects to follow DIY voice recognition kit Raspberry Pi computing cluster: What I'm using it for, and what I've added to it In the paper, Performance of a Low Cost Hadoop Cluster for Image Analysis, researchers Basit Qureshia, Yasir Javeda, Anis Kouba, Mohamed-Foued Sritic, and Maram Alajlan, built a 20 node RPi Model 2 cluster, brought up Hadoop on it, and used it for surveillance drone image analysis.
