Udacity and Cloudera recently partnered to create an online course titled “Introduction to Hadoop and MapReduce”.
I really like the course. It’s short and to the point. I think it’s a very good introduction for people new to Hadoop and wanting to get a bit of hands on.
I created a short YouTube video that walks someone through the first question in the final section of the course. It’s important to understand the concepts thought in the course, because they all need to be applied here.
