A Hadoop and Spark Cluster on Docker

Run Hadoop and Spark Cluster within Docker Containers

• This project is based on Blog: Run Hadoop Cluster in Docker Update

5 Nodes Hadoop&Spark Cluster

1. pull docker image

sudo docker pull silencebingo/hadoop-spark-cluster

2. clone github repository

git clone https://github.com/silencebingo/hadoop-spark-cluster

3. create hadoop network

sudo docker network create --driver=bridge hadoop

4. start container

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

5. start hadoop

./start-hadoop-spark.sh

6. test hadoop

./run-wordcount.sh

output

input file1.txt:
Hello Hadoop

input file2.txt:
Hello Docker

wordcount output:
Docker    1
Hadoop    1
Hello    2

7. test spark

output

Arbitrary size Hadoop cluster

1. pull docker images and clone github repository

do 1~3 like section A

2. rebuild docker image

sudo ./resize-cluster.sh 6

• specify parameter > 1: 2, 3..
• this script just rebuild hadoop image with different slaves file, which pecifies the name of all slave nodes

3. start container

sudo ./start-container.sh 6

• use the same parameter as the step 2

4. run hadoop cluster

do 5~6 like section A
