Fully Distributed Hadoop cluster installation in Ubantu 14.04 The purpose of this article is to teach you how to configure Hadoop's fully distributed cluster. In addition to completely distributed, there are two types: Single-node and pseudo-distributed deployment. Pseudo-distribution only requires one virtual machine, and there are relatively few configurations.

distributed programs without knowing the underlying details of the distribution. Take advantage of the power of the cluster to perform high-speed operations and storage. The core design of the Hadoop framework is HDFS and MapReduce. HDFS provides storage for massive amounts of data, and MapReduce provides calculations for massive amounts of data.BuildTo build a cluster
