Hadoop Primer – Yet Another Hadoop Introduction
I just came upon a pretty good Hadoop introduction paper posted on Sun’s wiki. Apache Hadoop is a free Java software framework that supports data intensive distributed applications. It enables applications to work with thousands of nodes and petabytes of data. Hadoop was inspired by Google's MapReduce and Google File System (GFS) (wikipedia). I wouldn’t call it an alternative to mysql – they’re in completely different weight categories. I like to think of Hadoop as a complement – I think it’s closer to memcached in its functions than to mysql. Perhaps a hybrid of both but a unique beast nonetheless. If you’re serious about scaling, you owe it to yourself to start exploring Hadoop yesterday.
A couple of reasons for sharing the primer:
- it is short and concise
- it has examples
- and most importantly, it finally pushed me to install Hadoop on a 4-machine cluster and start playing around with it
So, take a look at the primer PDF, download Hadoop, and quickstart it. Here’s a more detailed set up page.
The big guys are using it, why aren’t you?

Thanks for this, will tweet it for other Hadoop newbies.
