Fabio de MirandaEric Baldeschwieler from Yahoo gave an impressive talk about what they’re doing with Hadoop. Yahoo is running clusters at a simply amazing scale. They have several different clusters, totally some 86 PB of disk space, but their largest is a 4000-node cluster with 16 PB of disk, 64 TB of RAM, and 32,000 CPU cores. One of the most compelling points they made was that Yahoo’s experiences prove that Hadoop really does scale as designed. If you start with a small grid now, you can be sure that it will scale up – way up.
