First things first. Open your sources.list file and add the MapR repositories into it.
deb http://package.mapr.com/releases/v2.1.2/ubuntu/ mapr optional
deb http://package.mapr.com/releases/ecosystem/ubuntu binary/
Now, update your repository.
sudo apt-get update
Note : If it throws any error regarding MapR repositories, just uncomment the lines which allow us to add software from Canonical's partner repository.
## Uncomment the following two lines to add software from #Canonical's
## 'partner' repository.
