"Finishing Learning Hadoop" One of the basics of Hadoop Learning: Server Clustering Technology

Computing ClustersHigh-performance computing clusters, referred to as HPC clusters. Such clusters are dedicated to providing powerful computing power that a single computer cannot provide, including numerical computation and data processing, and tends to pursue comprehensive performance. HPG is similar to supercomputing, but different, and computing speed is the first goal of Supercomputing pursuit. The fastest speed, maximum storage, the largest volume, and the most expensive price represent t

Resource extension technology for Hadoop virtualization extension (hve)

Background In virtualized cloud environments, Hadoop can have better "resiliency", which is an important advantage of cloud computing, such as Amazon's EMR (elasticmapreduce) service, where users can quickly deploy a Hadoop cluster in the cloud to run computing tasks, And users can dynamically add or remove compute nodes to the cluster. There is a potential problem, HAODOP data nodes are not inherently "r
