I am trying to be familiar with Hadoop-MapReduce. After studying theoratical knowledge on this concepts, I want to do practise on them.
However, I could not find small data sets ( up to 3 Gb ) for this technology. Where can I find data sets in order to do practise ?
OR, How can I do practise Hadoop-MapReduce ? In other words, are there any tutorial or website which offers exercise ?
