I had been to a Hadoop training class over the weekend and since then I was spending my time to get Hadoop working over my Linux box. I have an Ubuntu LTS which is dual mounted on my windows laptop. When in the classroom. Cloudera was used to teach, I ventured with the Apache Hadoop on my Linux machine. I downloaded the latest Hadoop 2.X release and followed the link below to configure a single cluster to experiment,
And I am not going to list down the steps to configure here as you find lots of materials on the net to get it done. I am going to list down the issues I faced during this experimentation and its resolution.
Hadoop requires the SSH to be configured as a password less entry. While I was performing this step, I was about to configure the ssh env file. But to my surprise I could not find the file. There is a directory in /etc but there is no configuration files related to it. I later figured out that the ssh daemon was not running and it is because I have not installed it on my linux machine. So I did a sudo apt-get ssh to get the ssh daemons installed and then I can get it working with the steps on the above link.
