Ask HN: Learning by doing : Hadoop

Hi,

I picked up a Hadoop couple of months back and am finding different ways to use it so as to apply what I have learned so far (MapReduce, Hive, Pig, etc).

As Hadoop is really used in environments where the data to be queried is large, I started looking around for such kind of data. I came across the Wikipedia data (available for download).

Now I am trying to list out the questions that I could as this data.

What are the questions that you want answered from the data available in the Wikipedia data?

This will help me write some useful MapReduce code , Hive quries or Pig scripts to improve my skills.

I just feel that learning by doing is the best form of learning.

Thanks.
