Getting Things Ready

First, it is necessary to have Docker and Docker compose running on your OS.

Installing Docker

• Update yum repositories
  sudo yum check-update
• Get and execute installation script of Docker
  curl -fsSL https://get.docker.com/ | sh
• Start Docker, verify its status and make it available upon boot
  sudo systemctl start docker
sudo systemctl status docker
sudo systemctl enable docker
• An optional step: If you would like to run "docker" command without sudo, do the following (replace username with yours)
  sudo usermod -aG docker username
• Status should be similar to below
  

Installing Docker Compose

• Get epel repositories and install PIP
  sudo yum install epel-release
sudo yum install -y python-pip
• Install Docker Compose with PIP
  sudo pip install docker-compose
sudo pip install docker-compose --ignore-installed (in case you're running pip 10)
• Update python and PIP
  sudo yum upgrade python*
sudo pip install --upgrade pip

Setting up Single Node Cloudera Hadoop with Docker Compose

• Get the docker-compose.yaml file from https://github.com/emirkorkmaz/cloudera-quickstart-docker-compose/blob/master/cloudera-quickstart/docker-compose.yaml and store it in a proper folder
• Change directory to the folder where docker-compose.yaml exists
• Execute following command and wait for docker and docker compose do the things for you (If you dont want to see the trace simply execute the command on detach mode)
  docker-compose up
• In the end, you see following final lines that means your Single Node Cloudera Hadoop is ready to use
  
• Try to each and use Hue, http://IP:8888. User name and password is cloudera/cloudera
  
  

Start up Cloudera Manager

Having installation completed, Cloudera Manager is still disabled and it is better to enable it. Here is the simple guide for enabling Cloudera Manager

• List the quickstart container and attach to it
  docker ps
docker attach container-id
• Execute following command in container for enabling Cloudera Manager. It will take couple of minutes to be completed
  /home/cloudera/cloudera-manager --express
  
• When CM is being started, it stops all services. Hence it is necessary to restart them all over Cloudera Manager

and We're done! Single node Cloudera Hadoop is ready for use
