CentOS Hadoop-2.2.0 cluster installation Configuration
For a person who just started learning Spark, of course, we need to set up the environment and run a few more examples. Currently, the popular deployment is Spark On Yarn. As a beginner, I think it is necessary to go through the Hadoop cluster installation and conf
Introduction to Hadoop
Hadoop is an open source distributed computing platform owned by the Apache Software Foundation. With Hadoop Distributed File System (Hdfs,hadoop distributed filesystem) and MapReduce (Google MapReduce's Open source implementation) provides the user with a distributed infrastructure that is trans

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
Introduction
Recently, with the need for scientific research, Hadoop clusters have been built from scratch, including separate zookeeper and HBase.
For Linux, Hadoop and other related basic knowledge is relatively small, so this series of sharing applies to a variety of small white, want to experience the Hadoop cluster
