Hadoop Ecosystem

Industry news, partner stories, buzz and happenings

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.…

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.…

We get asked a lot of questions about how to select Apache Hadoop worker node hardware. During my time at Yahoo!, we bought a lot of nodes with 6*2TB SATA drives, 24GB RAM and 8 cores in a dual socket configuration. This has proven to be a pretty good configuration. This year, I’ve seen systems with 12*2TB SATA drives, 48GB RAM and 8 cores in a dual socket configurations. We will see a move to 3TB drives this year.…

While much credit has been given to Yahoo! since Hadoop was donated to the Apache Software Foundation in 2006, the real measure of their contributions and the impact that they have had in making Apache Hadoop what it is today is quite substantial. This blog will take a look at Yahoo!’s contributions to Apache Hadoop and the impact that those contributions have had on making Apache Hadoop what it is today.…

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.…

Delegation tokens play a critical part in Apache Hadoop security, and understanding their design and use is important for comprehending Hadoop’s security model.

Authentication in Apache Hadoop
Apache Hadoop provides strong authentication for HDFS data. All HDFS accesses must be authenticated:

1. Access from users logged in on cluster gateways
2. Access from any other service or daemon (e.g. HCatalog server)
3.…

Overview
As the former technical lead for the Yahoo! team that added security to Apache Hadoop, I thought I would provide a brief history.

The motivation for adding security to Apache Hadoop actually had little to do with traditional notions of security in defending against hackers since all large Hadoop clusters are behind corporate firewalls that only allow employees access. Instead, the motivation was simply that security would allow us to use Hadoop more effectively to pool resources between disjointed groups.…
