基于Docker搭建Hadoop集群, 用于学习

• ####在参考 博客: [基于Docker搭建Hadoop集群之升级版] 前提下从Ubuntu 更改成 Centos7 (http://kiwenlau.com/2016/06/12/160612-hadoop-cluster-docker-update/)

操作流程

1. pull docker 镜像

sudo docker pull kiwenlau/hadoop:1.0

2. clone github repository

git clone https://github.com/pkeropen/hadoop-docker.git

3. create hadoop network

sudo docker network create --driver=bridge hadoop

4. start container

cd hadoop-cluster-docker
sudo ./start-container.sh

output:

start hadoop-master container...
start hadoop-slave1 container...
start hadoop-slave2 container...
root@hadoop-master:~# 

• 开启3个容器 ,一个主容器, 二个副容器
• 同时进去主容器, 可以执行下一步命令

5. start hadoop

./start-hadoop.sh

6. run wordcount

./run-wordcount.sh
