As the release manager for the Apache Hadoop 2.0 release, it gives me great pleasure to share that the Apache Hadoop community has just released Apache Hadoop 2.0.0 (alpha)! While only an alpha release (read: not ready to run in production), it is still an important step forward as it represents the very first release that delivers new and important capabilities, including:

A very short while ago, Vinod blogged about some of the significant improvements in Hadoop.Next (a.k.a hadoop-0.23.1).

To recap, the Hortonworks and Yahoo! teams have done a huge amount of work to test, validate and benchmark Hadoop.Next, the next generation of Apache Hadoop that includes HDFS Federation, NextGen MapReduce (a.k.a. YARN) and many other significant features and performance improvements.

Today, I’m very excited to announce that the Apache Hadoop community voted to release hadoop-0.23.1 and it’s now available for all to use!…

Hortonworks and Teradata announced a strategic relationship today that includes joint go-to-market and development work to more closely integrate Hortonworks Data Platform with the Teradata Analytical Ecosystem. I wanted to take the opportunity to highlight this important partnership and share my thoughts on why this is an important milestone for Hortonworks and the larger Apache Hadoop community.

As somebody that has been heavily involved in the development of Apache Hadoop for six years and counting, it’s personally exciting to see Hadoop entering a new phase of adoption.…

As the Release Manager, it’s my privilege to present Apache Hadoop 0.23:

Release: http://hadoop.apache.org/common/releases.html
Documentation: http://hadoop.apache.org/common/docs/r0.23.0/

I’ll present a short overview of the release in this post, more details are available in my recent talk on Apache Hadoop 0.23 at Hadoop World, 2011.…

As the framework architects and developers of Apache Hadoop MapReduce, we are always looking for ways to simplify the complex tasks associated with large-scale processing of data. We want users and organizations to spend their time on analyzing their growing data to gain valuable insights, not on menial tasks such as massaging their data for consumption or tediously parsing complex structures in their data. The Informatica HParser technology is extremely valuable in this regard.…

Dennis M. Richie was a giant of our craft and a truly great teacher. Millions of folks owe their passion for programming to K&R. It literally started their careers.

We are very sad to hear that Dennis M. Ritchie passed away after a prolonged illness. We join others in offering our condolences to his family and hope he is in a more comfortable place.

Thank you so much. You’ve made such a difference to so many.…

There has been a lot of progress on hadoop-0.23. We’re continuing to crank through issues as we get ready to ship.

We are mostly past the initial challenges of moving our entire build infrastructure to Maven. Many thanks to Alejandro, Tom, Giri & Eric Yang for making it happen.

HDFS is nearly there:

  • HDFS Federation and Client-side mount tables have been tested with ~300 node clusters with security on.
  • HDFS upgrades have been tested from 0.20.2xx.

We are glad to have branched for a hadoop-0.23 release. We have already talked about some of the significant enhancements coming in the upcoming release such as HDFS Federation and NextGen MapReduce and we are excited to be starting the journey to begin stabilizing the next release. Please check out this presentation for more details.

As always, this is a community effort and we are very thankful for all the contributions from the Apache Hadoop community.…

For the first time in its history, OSCON, the premier open-source conference, had a special OSCON Data sub-conference. Apache Hadoop had a full track dedicated to it at OSCON Data. This clearly was indicative of the interest in Big Data and the central role Apache Hadoop plays in the space. A special shout out to Bradford Stephens and Sarah Novotny, the program chairs, who did a fantastic job with OSCON Data.…
