Through a combination of lecture and hands-on exercises you will learn how to install, configure, maintain […]

Since its first deployment at Yahoo in 2006, HDFS has established itself as the defacto scalable, reliable and robust file system for Big Data. It has addressed several fundamental problems of distributed storage at unparalleled scales and with enterprise grade robustness. As more and more enterprises adopt Apache Hadoop, it is becoming a unified central […]
