Raspberry Pi Cluster - A minimal setup to experiment with failure scenarios
Last night while reading Starting Small: Set Up a Hadoop Compute Cluster Using Raspberry Pis , I went from "Smells like geeky waste of time", to "Hmmm, actually this might teach you how to setup a cluster", to "wow, this setup might actually be the easiest way to experiment and learn about different failure scenarios: network latency, network failure, slow I/O, memory pressure".
