Presentation: Hadoop at Yahoo!
In case you are already a seasoned Hadoop engineer looking for what others are doing or you just prepare yourself to start learning about Hadoop by following this tutorial, it is still interesting to see how very large companies are using Hadoop. Yahoo!, the company that open sourced Hadoop, is probably running the largest install of Hadoop. Or is it Facebook?
Update: I have found the video from this presentation (thanks to Cloudera guys) so now you can watch the two in parallel.
