#### 3 Nodes Hadoop Cluster ####

###### 1. pull docker image ######

sudo docker pull kiwenlau/hadoop:1.0

###### 2. clone github repository ######

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

###### 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:~#

*  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
