Installing Hadoop 2.x on MAC (Yosemite)

After breaking my head on several videos and blogs i finally got it right.
To install hadoop 2.x on mac i would recommend you have
a) Java Installed (If java is not installed install JAVA JDK)
b) Password-less ssh
(Check by typing down below)

ssh localhost

If password-less ssh is not enabled
Ensure Remote Login under System Preferences -> Sharing is checked to enable SSH.

ssh-keygen -t rsa -P ""

cat $HOME/.ssh/ >> $HOME/.ssh/authorized_keys

ssh localhost

(Make sure you are able to ssh password less and while generating keys make sure its blank)
(For this tutorial we will configure Hadoop in psedu0-distributed mode --

Download Hadoop
Extract Hadoop

tar -xvzf ~/Downloads/hadoop-2.7.0.tar.gz

And edit the following in the configuration files

And VoilĂ  you have a petit Hadoop cluster for yourself.
