I relied on a paper from Michael Noll ( http:\/\/www.michael-noll.com\/tutorials\/running-hadoop-on-ubuntu-linux-single-node-cluster\/ ). I noticed it was really important to use the correct versions of the jdk; I first tried to install Hadoop 1.0.3 with a recent version of the Jdk but that failed. A subsequent attempt was successfull. This could be established with help of the interface ( localhost:50070 ).<br \/>\nA second attempt was about installing Hadoop 2.4. I used a blog from Matthew Sharpe ( http:\/\/dogdogfish.com\/2014\/04\/26\/installing-hadoop-2-4-on-ubuntu-14-04\/ ) to get the necessary information. After the installion, I created a small example to check if this worked. It did work.<\/p>\n<p>Hence, I ended up with two working examples of Hadoop. <\/p>\n<p>The problem is that hadoop is now alive and kicking. I verified this by executing a small example. This worked out ok. But how to continue. Working with hadoop isn&#8217;t trivial. My next step will be is finding a means to work with Hadoop.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Everyone talks about big data and Hadoop.
