"Hadoop: The Definitive Guide" Coming Soon

After a busy couple of months I've finished the writing for "Hadoop: The Definitive Guide". It's now going through the production process at O'Reilly.

You can pre-order it on Amazon and O'Reilly. You can also get the Rough Cuts version from O'Reilly to read today, although it hasn't yet been refreshed with my latest draft (I hope that will happen in the next few days).

Here's the final chapter listing. Readers of earlier drafts will notice that the number of chapters has grown: this is because the elephantine MapReduce chapter has been split into three (chapters 6, 7, and 8) to make things more digestible.

1. Meet Hadoop
2. MapReduce
3. The Hadoop Distributed Filesystem
4. Hadoop I/O
   
5. Developing a MapReduce Application
6. How MapReduce Works
7. MapReduce Types and Formats
8. MapReduce Features
9. Setting Up a Hadoop Cluster
10. Administering Hadoop
11. Pig
12. HBase
13. ZooKeeper
14. Case Studies
    

The writing's done but I still have to package up the example code. I'll be doing this soon, and it will appear on the book's website.

Draft Pig Chapter

A couple of quick updates on the Hadoop book I'm writing. The Pig chapter is now available on Safari. It still has a few holes, but I'd love to hear feedback on it.

Also included is a Hadoop case study from Last.fm. Thanks to Adrian Woodhead and Marc de Palol for writing it.

Hadoop Developer Zeitgeist

The Cloudera team have just released a website which has a few reports on various Hadoop development metrics. I like the Most Watched Open Jira Issues, as it gives a good summary of what Hadoop Core developers are thinking about.

Personally, I can't wait for the new MapReduce API (HADOOP-1230), which is currently the third most watched issue.

Cloudera

I'm pleased to announce that I've joined Cloudera, a new startup providing support for Hadoop. Amr Awadallah (who's one of the founders) has got more details in his blog post.

Hadoop: The Definitive Guide

Update: Fixed feedback link.

The Rough Cut of Hadoop: The Definitive Guide is now up on O'Reilly's site. There are a few chapters available already, at various stages of completion. Remember, it's still pretty rough. I'd love to hear any suggestions for improvements that you may have though. You can submit feedback from Safari where the book is hosted. As the Rough Cuts FAQ explains, I'd like feedback on missing topics, if something is not understandable, and technical mistakes.

Now I just need to go and write the rest of it...
