Deploying a Hadoop cluster for Test purposes using AWS EC2, Docker and Cloudera
What you need to complete this installation
A. Cloud platform: 1 AWS account
B. Tools used: 1 EC2 instance on AWS (Ubuntu 18.04 LTS)
C. Containerization: 1 Docker image (Cloudera Quickstart)
D. Programming language: Bourne Shell (bash)
Some of you asked me to make a gist that helps beginners with
Hadoop going to die as many claim?
If yes, then let's run a
Hadoop cluster before it's too late :)!
This gist will help you launch a
Hadoop cluster easily.
We'll be using
We'll also use
Docker in order to launch
At the end of this gist, you'll have a
Hadoop cluster up and running for basic purposes.
I recommend you to use a regular or enterprise version of
Before you start
Create an account on
AWSand log into
AWS Management Console.

This section must be considered before taking the README.md section of this gist.
We'll first set up a security group, a user and assign an IAM role before proceeding to the concrete installation of Hadoop.
Go to Services > EC2, in NETWORK AND SECURITY, click on Security Groups > Create Security Group
Security group name: Hadoop
VPC: select default VPC
Security Group Rules (Inbound and Outbound): allow
HTTPS from anywhere.
Click on Create.
Go to Services, in Security, Identity and Compliance section, click on
Click on Users > Add user and configure as follows:
Click on Next: Permissions > Add user to group > Create group > Group Name: hadoop_admins
AmazonEC2FullAccess, Search for
IAM go to
Roles > Create role > click on EC2 > Next: Permissions > select AdministratorAccess
Key: name > Value: hadoop-cluster > Next: Review > Role name: AdminAccess > Create role. By clicking on
IAM, you can have a summary of the role you've created.
At this stage you should have a user, a group and a role attached to your
AWS account before proceeding to step 2.
Please note: having all check marks on
IAM green is great, but it is not mandatory by
Steps to be covered: 3
Setting up our EC2 instance
Pulling a Cloudera Quickstart Docker Image
Starting the services
Go to Services > EC2, click on Launch Instance.
Ubuntu server 18.04 LTS as AMI.
t2.xlarge instance type. Choosing a lower instance may lead to latency.
Click on Configure Instance Details and tune as follows:
Number of instances: 1 > IAM role: AdminAccess > Next: Add Storage, set storage size to 30 Gibibytes.
Next: Add tags > Key: name, Value: hadoop-cluster > Next: Configure Security Group > select an existing security group:
choose the one you've created with the above commands. You can also select your default security group.
Review and Launch > Launch.
You'll be prompted by AWS to create a Key Pair file, create a new key pair file and Download it.
Save it on a repository called hadoop:
Go to Services > EC2, wait for your instance to be running and for the health checks to pass.
When your instance is running, select your instance name, and click "Connect".
Copy the link provided by the EC2 instance and use it in your Terminal:
ssh -i "MyKeyPairFile.pem" ubuntu@ec2-*-*-*-*.compute-1.amazonaws.com
Open your Terminal and go the the repository where you've stored the Key Pair file.
Perform as follows:
chmod 400 MyKeyPairFile.pem
Now execute the given ssh command by your EC2 instance:
ssh -i "MyKeyPairFile.pem" firstname.lastname@example.org
You are now logged into your EC2 instance's terminal and ready to install Docker and Cloudera Quickstart.
sudo apt-get remove docker docker-engine docker.io
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable"
sudo apt-get update
apt-cache madison docker-ce
sudo apt install docker.io
sudo systemctl start docker
sudo systemctl enable docker
docker pull cloudera/quickstart:latest
docker run -m 4G --memory-reservation 2G --memory-swap 8G --hostname=quickstart.cloudera --privileged=true -t -i -v $(pwd):/CDH --publish-all=true -p8888 -p8088 cloudera/quickstart /usr/bin/docker-quickstart
If all services are launched on your EC2 Terminal, open your web browser and type the following :
You should land to the login form, use
cloudera / cloudera as login and password.
Here you go! You can now start using
Hadoop for testing purposes.
