The 2012 Strata + Hadoop World conference was week before last in New York City. Cloudera co-presented the conference with O’Reilly Media this year, and we were really pleased with how the event turned out. Of course we launched Cloudera Impala, but there was a ton of news from companies across the Apache Hadoop ecosystem. Andrew Brust over at ZDNet wins the prize for comprehensive coverage of all the announcements.
Today we bring you a brief interview with Alex Holmes, author of the new book, Hadoop in Practice (Manning). You can learn more about the book and download a free sample chapter here.
There are a few good Hadoop books on the market right now. Why did you decide to write this book, and how is it complementary to them?
When I started working with Hadoop I leaned heavily on Tom White’s excellent book,
I am very pleased to announce the availability of Cloudera Manager 4.1. This release adds support for the Cloudera Impala beta release, and management and monitoring of key CDH features.

After a long period of intense engineering effort and user feedback, we are very pleased, and proud, to announce the Cloudera Impala project. This technology is a revolutionary one for Hadoop users, and we do not take that claim lightly.
When Google published its Dremel paper in 2010, we were as inspired as the rest of the community by the technical vision to bring real-time, ad hoc query capability to Apache Hadoop,
Today we’re proud to announce a new addition to the Apache Hadoop ecosystem: Cloudera Impala, a parallel SQL engine that runs natively on Hadoop storage. The salient points are:
- Hive compatible
- 10x the performance of Hive/MapReduce, on average
- 100% open source, under the Apache License v2 – just like Hadoop
- Tested to run on CDH4.1 or higher
There’s a blog post that follows mine that provides more details about Impala and how it works.
