Posts categorized by : Hadoop Ecosystem

As the Hadoop ecosystem has exploded into many projects, searching for the right answers when questions arise can be a challenge. Thats why I was thrilled to hear about search-hadoop.com, from Sematext. It has a sister site called search-lucene where you can… search lucene!

Search-Hadoop.com searches across projects – JIRAs, source code, mailing lists, wikis, etc. so you can see design and API docs, as well as questions, answers and general documentation.…

Hadoop featured prominently at Stanford’s annual XLDB conference last week, as representatives from academia and industry gathered to discuss Extremely Large Databases. The conference program, with slides are available: http://www-conf.slac.stanford.edu/xldb2012/ProgramC.asp. A highly technical lineup presented on Big Data in biology and physics, and cloud computing and Hive in particular were topic areas.

Hortonworks’ own Ashutosh Chauhan @ashutoshchauhan, an Apache Pig, Hive and HCatalog committer, presented ‘Hive vs Pig: Similarities and Differences‘ (slides).…

Partner Webinar Series

On September 18 at 10am PT/1pm ET we join our partner Datameer in a webcast aimed at providing answers to some common questions we hear in the industry. Specifically, what are some of the use cases that big data analytics is perfect for?

By looking at some common uses we are seeing, you’ll be able to envision how you can leverage the analytics results from your own data.…

Partner Webinar Series

Hortonworks boasts a rich and vibrant ecosystem of partners representing a huge array of solutions that leverage Hadoop, and specifically Hortonworks Data Platform, to provide big data insights for customers. The goal of our Partner Webinar Series is to help communicate the value and benefit of our partners’ solutions and how they connect and use Hortonworks Data Platform.

Look to the Clouds

Setting up a big data cluster can be difficult, especially considering the assembly of all the all the equipment, power, and space to make it happen.…

Twitter Analytics presented their distributed infrastructure, including Hadoop and Pig, at a UC Berkeley iSchool special course called INFO 290: Analyzing Big Data with Twitter. Twitter is a major contributor to many Apache projects. The course was over-subscribed and was a great success, as students got to learn from practicing data scientists using Hadoop on truly massive datasets. The entire lecture series is available here.

Bill Graham @billgraham, a Data Systems Engineer at Twitter Analytics and Apache Pig committer, presented an Introduction to Hadoop.…

The August Pig Hackathon brought Pig users from Hortonworks, Yahoo, Cloudera, Visa, Kaiser Permanente, and LinkedIn to Hortonworks HQ in Sunnyvale, CA to talk and work on Apache Pig.

Jonathan Coveney and Bill Graham from Twitter walked newer Pig users through how Pig translates a Pig Latin script to map reduce jobs and went over how to read the output of explain. For those interested, Hortonworks founder Alan Gates covers this in Chapter 1 of Programming Pig.…

Pre-crime? Pretty close…

If you have seen the futuristic movie Minority Report, you most likely have an idea of how many factors and decisions go into crime prevention. Yes, Pre-crime is an aspect of the future but even today it is clear that many social, economic, psychological, racial, and geographical circumstances must be thoroughly considered in order to make crime prediction even partially possible and accurate. The predictive analytics made possible with Apache Hadoop can significantly benefit this area of government security.…

This is the first part of a series written by Charles Boicey from the UC Irvine Medical Center.  The series will demonstrate a real case study for Apache Hadoop in healthcare and also journal the architecture and technical considerations presented during implementation.

With a single observation in early 2011, the Hadoop strategy at UC Irvine Medical Center started. While using Twitter, Facebook, LinkedIn and Yahoo we came to the conclusion that healthcare data although domain specific is structurally not much different than a tweet, Facebook posting or LinkedIn profile and that the environment powering these applications should be able to do the same with healthcare data.…

Nothing happens in a vacuum anymore.  Cities now have the ability to use information collected from a massive variety of sources in order help solve common city problems.  The information can arise from anywhere – tweets, blog posts, and meter readings all can serve to inform public officials (and citizens as a whole) about how to better interact in a data-drenched world.

Most famously, IBM’s Smart Cities initiative looks at how city governments meet the needs of their expanding populations by using available resources more efficiently. …

Earlier, in the “Big Data in Genomics and Cancer Treatment” blog post, I explored how the extensive amount of information in DNA analysis mostly comes from the vast array of characteristics associated with people’s DNA make up and with different cancer variations. The case with today’s healthcare is very similar. Each patient is unique and has thorough medical history records that allow doctors to make evaluations and recommendations for future treatments.…

Small companies, big data.

Big data is sometimes at odds with the business-savvy entrepreneur who wants to exploit its full potential.   In essence, the business potential of big data is the massive (but promising) elephant in the room that remains invisible because the available talent necessary to take full advantage of the technology is difficult to obtain.

Inventing new technology for the platform is critical, but so too is making it easier to use.…

Last week was an important milestone for Hortonworks: our one year anniversary. Given all of the activity around Apache Hadoop and Hortonworks, it’s hard to believe it’s only been one year. In honor of our birthday, I thought I would look back to contrast our original intentions with what we delivered over the past year.

Hortonworks was officially announced at Hadoop Summit 2011. At that time, I published a blog on the Hortonworks Manifesto.…

The following is Part 2 of 2 on data in education. The first article introduces the concept and application of data in education. The second article looks at recent movements by the Department of Education in data mining, modeling and learning systems.

Big data analytics are coming to public education. In 2012, the US Department of Education (DOE) was part of a host of agencies to share a $200 million initiative to begin applying big data analytics to their respective functions.…

Big Data Shopping Bag

With big data basking in the limelight, it is no surprise that large retailers have been closely watching its development… and more power to them! By learning to effectively utilize big data, retailers can significantly mold the market to their advantage, making themselves more competitive and increasing the likelihood that they will come out on top as a successful retailer. Now that there are open source analytical platforms like Hadoop, which allow for unstructured data to be transformed and organized, large retailers are able to make smart business decisions using the information they collect about customers’ habits, preferences, and needs.…

We’re heading to our very first OSCON conference to talk all things Apache Hadoop, the biggest gathering for the entire open source community in Portland, Oregon, and we would love to meet you there!

Meet our founders, Arun Murthy and Mahadev Konar, along with others from the Hortonworks team at this year’s conference.

There are many ways to meet the Hortonworks team and we would love to chat with you about how you are considering using Hadoop.…
