Nodes Hadoop Cluster

#####1. pull docker image

sudo docker pull joway/hadoop-cluster

#####2. clone github repository

git clone https://github.com/joway/hadoop-cluster-docker

#####3. create hadoop network

sudo docker network create --driver=bridge hadoop

#####4. start container

Linux/Mac OS

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

Windows

open the repo directory by powershell and run .\start-container.ps1 output:

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

• start 3 containers with 1 master and 2 slaves
• you will get into the /root directory of hadoop-master container

#####5. start hadoop

./start-hadoop.sh

#####6. run wordcount

./run-wordcount.sh

output

input file1.txt:
Hello Hadoop

input file2.txt:
Hello Docker

wordcount output:
Docker    1
Hadoop    1
Hello    2

7. sync src

本地目录: ~/src/

hadoop master 目录 : /root/src/

将代码copy到本地目录 ~/src/ 中, 但凡在该目录下的任何操作都会自动实时映射到 hadoop master 容器中的 /root/src/ 中

之后只要在本地~/src/中修改编辑代码, 在容器内执行命令即可

8.

相关便捷脚本:

1. ./build_image.sh 构建你的新镜像 ( 修改 Dockerfile 后 )
2. ./enter_master_bash.sh 进入hadoop_master 容器
3. ./delete_all_container.sh 清空所有docker容器 下面这些是windows的脚本
4. ./build_image.ps1 构建你的新镜像 ( 修改 Dockerfile 后 )
5. ./enter_master_bash.ps1 进入hadoop_master 容器
6. ./delete_all_container.ps1 清空所有docker容器
