Visualization on Impala: Big, Real-Time, and Raw

The guest post below is provided by Justin Langseth, Founder & CEO of Zoomdata, Inc. Thanks, Justin!

What if you could affordably manage billions of rows of raw Big Data and let typical business people analyze it at the speed of thought in beautiful, interactive visuals? What if you could do all the above without worrying about structuring that data in a data warehouse schema, moving it, and pre-defining reports and dashboards? With the approach I’ll describe below, you can.

How Improved Short-Circuit Local Reads Bring Better Performance and Security to Hadoop

One of the key principles behind Apache Hadoop is the idea that moving computation is cheaper than moving data — we prefer to move the computation to the data whenever possible, rather than the other way around. Because of this, the Hadoop Distributed File System (HDFS) typically handles many “local reads” reads where the reader is on the same node as the data:

Spotlight: How National Institutes of Health Advances Genomic Research with Big Data

This week, I’d like to shine a spotlight on innovative work the National Institutes of Health (NIH) is working on, leveraging Big Data, in the area of genomic research. Understanding DNA structure and functions is a very data-intensive, complex, and expensive undertaking. Apache Hadoop is making it more affordable and feasible to process, store, and analyze this data, and the NIH is embracing the technology for this reason. In fact, it has initiated a Big Data center of excellence — which it calls Big Data to Knowledge (BD2K) — to accelerate innovations in bioinformatics using Big Data, which will ultimately help us better understand and control various diseases and disorders.

Bob Gourley — a friend of Cloudera’s who wears many hats including publisher of CTOvision.com, CTO of Crucial Point LLC, and GigaOm analyst — recently interviewed Dr. Mark Guyer, the deputy director of the NIH’s National Human Genome Research Institute (NHGRI), about the BD2K effort.

Flexpod Select with Cloudera

Earlier this week, our partners NetApp and Cisco announced the Flexpod Select Family with support for Cloudera’s Distribution including Apache Hadoop (CDH).

We’re looking forward to the expansion of Flexpod Select to include Hadoop, as it provides additional options for customers to consume the benefits of the Cloudera Enterprise platform.

Cloudera at Strata + Hadoop World 2013

Strata Conference + Hadoop World 2013 is looming on the horizon and pacing to be the largest gathering of Big Data professionals on the globe. As co-hosts with O’Reilly, we have seen the conference thrive, grow, and are excited about the upcoming Oct. 28 – 30 event!

This Month in the Ecosystem

The ecosystem is evolving at a rapid pace – so rapidly, that important developments are often passing through the public attention zone too quickly. Thus, we think it might be helpful to bring you a digest (by no means complete!) of our favorite highlights on a regular basis. (This effort, by the way, has different goals than the fine Hadoop Weekly newsletter, which has a more expansive view – and which you should subscribe to immediately, as far as we’re concerned.)

Find the first installment below. Although the time period reflected here is obviously more than a month long, we have some catching up to do before we can move to a truly monthly cadence.

Customer Spotlight: Cerner’s Ryan Brush Presents “Thinking in MapReduce” at StampedeCon

For those of you attending this week’s StampedeCon event in St. Louis, I’d encourage you to check out the “Thinking in MapReduce” session presented by Cerner’s Ryan Brush. The session will cover the value that MapReduce and Apache Hadoop offer to the healthcare space, and provide tips on how to effectively use Hadoop ecosystem tools to solve healthcare problems.

Big Data challenges within the healthcare space stem from the standard practice of storing data in many siloed systems. Hadoop is allowing pharmaceutical companies and healthcare providers to revolutionize their approach to business by making it easier and more cost efficient to bring together all of these fragmented systems for a single, more accurate view of health. The end result: smarter clinical care decisions, better understanding of health risks for individuals and populations, and proactive measures to improve health and reduce healthcare costs.

Announcing Parquet 1.0: Columnar Storage for Hadoop

We’re very happy to re-publish the following post from Twitter analytics infrastructure engineering manager Dmitriy Ryaboy (@squarecog).

In March we announced the Parquet project, the result of a collaboration between Twitter and Cloudera intended to create an open-source columnar storage format library for Apache Hadoop.

With Sentry, Cloudera Fills Hadoop’s Enterprise Security Gap

Every day, more data, users, and applications are accessing ever-larger Apache Hadoop clusters. Although this is good news for data driven organizations overall, for security administrators and compliance officers, there are still lingering questions about how to enable end-users under existing Hadoop infrastructure without compromising security or compliance requirements.

While Hadoop has strong security at the filesystem level, it lacks the granular support needed to adequately secure access to data by users and BI applications. Today, this problem forces organizations in industries for which security is paramount (such as financial services, healthcare, and government) to make a choice: either leave data unprotected or lock out users entirely. Most of the time, the preferred choice is the latter, severely inhibiting access to data in Hadoop.

Customer Spotlight: Motorola Mobility’s Award-Winning Unified Data Repository

The Data Warehousing Institute (TDWI) runs an annual Best Practices Awards program to recognize organizations for their achievements in business intelligence and data warehousing. A few months ago, I was introduced to Motorola Mobility’s VP of cloud platforms and services, Balaji Thiagarajan. After learning about its interesting Apache Hadoop use case and the success it has delivered, Balaji and I worked together to nominate Motorola Mobility for the TDWI Best Practices Award for Emerging Technologies and Methods. And to my delight, it won!

Chances are, you’ve heard of Motorola Mobility. It released the first commercial portable cell phone back in 1984, later dominated the mobile phone market with the super-thin RAZR, and today a large portion of the massive smartphone market runs on its Android operating system.
