how to setup hadoop cluster

Objective:Some time ago to learn how to deploy a pseudo-distributed model of the Hadoop environment, because the work is busy, learning progress stalled for some time, so today to take the time to learn the results of the recent and share with you.This article is about how to use VMware to build your own Hadoop cluster. If you want to know about pseudo-distribute

Introduction to Hadoop Hadoop is an open-source distributed computing platform under the Apache Software Foundation. Hadoop, with Hadoop Distributed File System (HDFS, Hadoop Distributed Filesystem) and MapReduce (open-source implementation of Google MapReduce) as the core,

Originally thought to build a local programming test Hadoop program Environment is very simple, did not expect to do a lot of trouble, here to share steps and problems encountered, I hope everyone smooth.I. To achieve the purpose of connecting a Hadoop cluster and being able to encode it requires the following preparation:1. Remote

Build a Hadoop distributed cluster (Environment: Linux virtual machine) 1. Preparations: (Plan the host name, ip address, and usage. Set up three hosts first, and add four hosts dynamically. In the usage column, you can also set namenode, secondaryNamenode, and jobTracker Separate deployment, depending on actual needs, not unique) Host Name machine ip usage Cloud01 192.168.1.101 namenode/secondaryNamenode/j
