The Hortonworks Blog

I spent some time last week at ApacheCon NA 2011 in Vancouver, BC. It was a good experience and I enjoyed catching up with friends and colleagues involved in the Hadoop project and also meeting some of the executives of the Apache Software Foundation in person. It is clear that the Apache community is thriving and that interest in Hadoop remains very high.

Hortonworks is committed to supporting Apache and we are pleased to have been a gold sponsor of this event. …

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.…

Back in late June when Hortonworks was officially announced at Hadoop Summit, we explained that our strategy was going to focus on accelerating the development and adoption of Apache Hadoop. We made bold statements about the opportunities that Apache Hadoop had to become the de facto platform for big data. We even predicted that half of the world’s data would be processed by Apache Hadoop within five years.

We also talked about how in order for all of that to happen, we needed to address the technical and knowledge gaps that exist.…

I just spent a day at the Apache Lucene Eurocon conference in Barcelona. I gave a keynote presentation on how the Apache Lucene & Solr communities had a lot to gain from Apache Hadoop and how Hadoop could also gain from their contributions and technology. It was a good show and it was great to have a chance to meet the Lucid Imagination folks and others in the Apache search community.…

If when we started building an Apache Hadoop team at Yahoo!, someone had told me that in the future we would partner with Microsoft to improve Hadoop’s performance on Windows, I would have found the prediction hard to believe. The first time a Microsoft executive suggested that they would like to work with us to improve Apache Hadoop, I told them I found their proposal “mind-bending”. I also told them that if we could do it the right way, I liked the idea.…

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.…

We are very excited to enter into a strategic relationship with Microsoft to help bring Apache Hadoop to Windows customers. We are equally pleased that Microsoft will also work closely with the Hadoop community and propose contributions back to the Apache Software Foundation and the Hadoop project.

Hortonworks will provide Microsoft with important Hadoop support and training that will help accelerate the delivery of Apache Hadoop for Windows Server and Windows Azure, including insight into feature roadmap and designs, feedback on code reviews and regression and acceptance testing.…

Several weeks ago, Hortonworks published a blog post that highlighted the tremendous contributions that Yahoo has made to Hadoop over the years. The point was two-fold: 1) to pay homage to our former employer, and 2) to clarify that Yahoo will continue to be a major contributor to Hadoop.

Earlier this week, Cloudera responded to our post, calling it a misleading story. While we generally don’t comment on another vendor’s blogs, even if they assert things that we find questionable, we felt we had to respond to this one.…

Oracle embraced Apache Hadoop this week with the announcement of the Oracle Big Data Appliance that includes an open source distribution of Apache Hadoop.

We welcome Oracle to the Apache Hadoop community and look forward to their participation in the growing Hadoop ecosystem.  We hope that Oracle will commit to using the official releases of Hadoop from the Apache Foundation.  We believe that such a commitment will allow their customers to extract the most possible value from their Hadoop Appliances and facilitates the rapid growth of the Hadoop ecosystem.…

Hi Folks,

Hortonworks is a fast-growing software company that is looking for new talent that can make a positive impact on our company whether in development, QA and test, support and training or on the business side of the operations.  We recently updated the careers section of our website, adding a number of exciting job openings. We are very interested in filling each of these roles with great people as soon as possible.…

I’m pleased to announce that we’ve become a sponsor of the Apache Software Foundation (ASF). The ASF has been fundamental to Apache Hadoop’s success and our team’s ability to meet our goals since the inception as the Yahoo! Hadoop team in 2006. This is why we convinced Yahoo! to become a Apache Platinum Sponsor back in 2007, which it remains to this day. Now that we are operating as an independent company and continuing to benefit from Apache’s support, we made it a priority to continue to sponsor Apache.…

Apache Hadoop is equipped with a robust and scalable security infrastructure. It is being used at some of the biggest cluster installations in the world, where hundreds of terabytes of sensitive and critical data are processed every day.

Owen O’Malley provided a nice overview of Apache Hadoop security in his blog Motivations for Apache Hadoop Security. Devaraj Das also covered some of the core pieces of Apache Hadoop’s security architecture in his blog The Role of Delegation Tokens in Apache Hadoop Security.…

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.

Interest in Hortonworks and Apache Hadoop continues to rise. This past week, I presented at two conferences and had a number of requests to share our slides. Both presentations are now posted on slideshare.net and linked to in this blog.

The first conference was the Cowen Big Data Day in New York City. The slides for this presentation are available here. The Cowen Group is a leading financial services and investment banking firm.…

I ran across an interesting problem in my attempt to implement random forest using Apache Pig. In random forest, each tree is trained using a bootstrap sample. That is, sample N cases at random out of a dataset of size N, with replacement.

For example, here is the input data:
(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

Here is one bootstrap sample drawn from input:
(5, 2, 3, 2, 3, 9, 7, 3, 0, 4)

Each element can appear 0 to N times.…
