Cloudera Engineering Interns Got Talent

As is their custom, Cloudera Engineering’s interns made innovation, especially for Apache Spark, the theme of the Summer season.

Cloudera has a long-time tradition of searching far and wide for the smartest summer engineering interns that it can find. Alumni of the program have become start-up co-founders, faculty at top-tier CS departments, employees at other prominent technology companies (including Google, Databricks, Uber, LinkedIn), as well as many current employees at Cloudera. See some examples here.

Ph.D. Interns at Cloudera: Bringing Big Data Back to School

The following is a series of stories from people who in the recent past worked as Engineering Interns at Cloudera. These experiences concretely illustrate how collaboration between commercial companies like Cloudera and academia, such as in the form of these internships, helps promote big data research at universities. (These experiences were previously published in the ACM student journal, XRDS.)

This Month in Data Science

Data science has been a ubiquitous topic of conversation in the IT and business worlds across the month of November. In this brief post, I’ll bring you just a small cross-section of the data science meme on the Interwebs in the past 4 weeks:

The "Ask Bigger Questions" Contest!

Have you helped your company ask bigger questions? Our mission at Cloudera University is to equip Hadoop professionals with the skills to manage, process, analyze, and monetize more data than they ever thought possible.

Over the past three years, we’ve heard many great stories from our training participants about faster cluster deployments, complex data workflows made simple, and superhero troubleshooting moments. And we’ve heard from executives in all types of businesses that staffing Cloudera Certified professionals gives them confidence that their Hadoop teams have the skills to turn data into breakthrough insights.

Data Science: Hot or Not?

You may have noticed that Harvard Business Review is calling data science “the sexiest job of the 21st century.” So our answer to the question is: Hot. Definitely hot. 

If you need an explanation, watch the “Definition of a Data Scientist” talk embedded below from Cloudera data science director Josh Wills, which was hosted by Cloudera partner Lilien LLC recently in Portland, Ore. The key take-away is, you don’t literally have to be a “scientist,” just someone with the curiosity of one.

Caching in Apache HBase: SlabCache

This was my summer internship project at Cloudera, and I’m very thankful for the level of support and mentorship I’ve received from the Apache HBase community. I started off in June with a very limited knowledge of both HBase and distributed systems in general, and by September, managed to get this patch committed to HBase trunk. I couldn’t have done this without a phenomenal amount of help from Cloudera and the greater HBase community.


The amount of memory available on a commodity server has increased drastically in tune with Moore’s law. Today, its very feasible to have up to 96 gigabytes of RAM on a mid-end, commodity server. This extra memory is good for databases such as HBase which rely on in memory caching to boost read performance.

How I found Apache Hadoop

This is a guest post contributed by Loren Siebert. Loren is a San Francisco entrepreneur and software developer, and is currently the technical lead for the USASearch program.

A year ago I rolled my first Apache Hadoop system into production. Since then, I’ve spoken to quite a few people who are eager to try Hadoop themselves in order to solve their own big data problems. Despite having similar backgrounds and data problems, few of these people have sunk their teeth into Hadoop. When I go to Hadoop Meetups in San Francisco, I often meet new people who are evaluating Hadoop and have yet to launch a cluster. Based on my own background and experience, I have some ideas on why this is the case.

My Internship at Cloudera

David joined us as part of our intern program, and built the prototype for the distributed log search functionality that’s available as part of Cloudera Manager 3.7. He did an awesome job, and wrote the following blog post which, now that CM3.7 has been released, we’re pleased to publish.

The project

My intern project was to build a log searching tool, specialized for Apache Hadoop. My mini-app allows Hadoop cluster admins and operators to search their error logs across many machines, filter by time range, text in the log message, and find the namenode machine, for example. The results are then ordered by time, and shown to the user.

Hadoop World 2011: A Glimpse into Development

The Development track at Hadoop World is a technical deep dive dedicated to discussion about Apache Hadoop and application development for Apache Hadoop. You will hear committers, contributors and expert users from various Hadoop projects discuss the finer points of building applications with Hadoop and the related ecosystem. The sessions will touch on foundational topics such as HDFS, HBase, Pig, Hive, Flume and other related technologies. In addition, speakers will address key development areas including tools, performance, bringing the stack together and testing the stack. Sessions in this track are for developers of all levels who want to learn more about upcoming features and enhancements, new tools, advanced techniques and best practices.

My Summer Internship at Cloudera

This post was written by Daniel Jackoway following his internship at Cloudera during the summer of 2011.

When I started my internship at Cloudera, I knew almost nothing about systems programming or Apache Hadoop, so I had no idea what to expect. The most important lesson I learned is that structured data is great as long as it is perfect, with the addendum that it is rarely perfect.

Cloudera in The Cube with Silicon Angle TV at Strata Conference 2011

The consensus from the Cloudera attendees of the O’Reilly Strata Conference last week was that the data-focused conference was nearly pitch perfect for the data scientist, practitioners and enthusiast who attended the event. It was filled with educational and sometimes entertaining sessions, provided ample time for mingling with vendors and attendees and was well run in general.

One of the cool activities happening at the conference was live streaming video brought to us from the good folks at SiliconAngle. Using a mobile production system called The Cube, Silicon Angle hosts John Furrier (@furrier) and Dave Vellante interviewed industry luminaries and up and comers while bringing their own perspective. After streaming live for nearly two days these hosts are still able to keep the energy high and the tone light.

Top 10 Blog Posts of 2010

We blogged about 104 different topics in 2010 and we recently decided to take a look back and see what folks were most interested in reading.  The topics that were featured ranged from Cloudera’s Distribution for Apache Hadoop technical updates (CDH3b3 being the most recent) to highlighting upcoming Hadoop related events and activities to sharing practical insights for implementing Hadoop. We also featured a number of guest blog posts.

Here are the top 10 blog posts from 2010:

Cloudera Fun & Frightful Halloween Festivities

Here at Cloudera we embraced the holiday spirit with the light heartedness that is Halloween by hosting several activities including an engineering hack-a-thon, a hack-a-pumpkin-a-thon, and a costume competition.

What is in our Kitchen?

If there is one thing that chefs are proud of, it’s their kitchens. Whether cavernous top-of-the-line affairs or cramped New York apartments, kitchens are the place where raw ingredients are combined with talent and hard work to produce results. The only difference in the world of software is what you will find in our kitchens.  (more…)

How to Get a Job at Cloudera

We’re doing a lot of hiring at Cloudera — we have jobs open in operations, sales, engineering and elsewhere. Hiring well is hard work. We spend a lot of time on it, and have learned a lot about the kind of people we want to bring in. One of the best ways for us to do a good job of hiring is to help you do a good job of applying for a job here.

I’ll begin the post, though, by telling you what doesn’t work. Several times a day, we get an unsolicited email or phone message from a contingency recruiter like this one:
