As you know, Install Hadoop is not easy. And It require a virtual machine with high configuration. In my post, I will give you the shortest way to have Hadoop in your machine. It is installation via Docker. I assume that you had Docker in your Ubuntu 14.04
If your dreams do not scare you. They are too small.
Prerequisites
