How to install and running Cloudera Docker Container on Ubuntu

This tutorial will show how to install and configure version 5.7.0 of Cloudera Distribution Hadoop (CDH 5) on Ubuntu 16.04 host using Docker.

What’s CDH?

CDH (Cloudera’s Distribution Including Apache Hadoop) is the most complete, tested, and widely deployed distribution of Apache Hadoop. CDH is 100% open source and is the only Hadoop solution to offer batch processing, interactive SQL and interactive search as well as enterprise-grade continuous availability. More enterprises have downloaded CDH than all other distributions combined.

Why Docker?

Getting down to the nuts and bolts, Docker allows applications to be isolated into containers with instructions for exactly what they need to survive that can be easily ported from machine to machine. Virtual machines also allow the exact same thing. While Docker has a more simplified structure compared to both of these, the real area where it causes disruption is resource efficiency.

Install Docker

Installing docker is very easy. The choice here is Ubuntu 16.04, so before start with the installation takes into consideration the requirements then follow this guide.

Uninstall old versions

Older versions of Docker were called docker or docker-engine. If these are installed, uninstall them:

$ sudo apt-get remove docker docker-engine docker.io

The contents of /var/lib/docker, including images, containers, volumes, and networks, are preserved. Check the content using these commands below.

$ sudo ls /var/lib/docker

Install using the repository

Set up the repo

Update the apt package index, install packages to allow apt to use a repository over HTTPS, and add Docker’s official GPG key:

$ sudo apt-get update
$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

$ sudo apt-key fingerprint 0EBFCD88
