Hadoop is in the Mind of the Beholder

by Merv Adrian  |  March 24, 2014  |  11 Comments

This post was jointly authored by Merv Adrian (@merv) and Nick Heudecker (@nheudecker) and appears on both blogs. In the early days of Hadoop (versions up through 1.x), the project consisted of two primary components: HDFS and MapReduce. One thing to store the data in an append-only file model, distributed across an arbitrarily large number […]

AAA is Not Enough Security in the Big Data Era

by Merv Adrian  |  January 13, 2014  |  11 Comments

Talk to security folks, especially network ones, and AAA will likely come up. It stands for authentication, authorization and accounting (sometimes audit). There are even protocols such as Radius (Remote Authentication Dial In User Service, much evolved from its first uses) and Diameter, its significantly expanded (and punnily named) newer cousin, implemented in commercial and […]

BYOH – Hadoop’s a Platform. Get Used To It.

by Merv Adrian  |  October 9, 2013  |  9 Comments

When is a technology offering a platform? Arguably, when people build products assuming it will be there. Or extend their existing products to support it, or add versions designed to run on it. Hadoop is there. The age of Bring Your Own Hadoop (BYOH) is clearly upon us.  Specific support for components such as Pig […]

What, Exactly, Is “Proprietary Hadoop”? Proposed: “distribution-specific.”

by Merv Adrian  |  September 6, 2013  |  12 Comments

Many things have changed in the software industry in an era when the use of open source software has pervaded the mainstream IT shop. One of them is the significance – and descriptive adequacy – of the word “proprietary.” Merriam-Webster defines it as “something that is used, produced, or marketed under exclusive legal right of […]

Hadoop Summit Recap Part Two – SELECT FROM hdfs WHERE bigdatavendor USING SQL

by Merv Adrian  |  July 15, 2013  |  10 Comments

Probably the most widespread, and commercially imminent, theme at the Summit was “SQL on Hadoop.” Since last year, many offerings have been touted, debated, and some have even shipped. In this post, I offer a brief look at where things stood at the Summit and how we got there. To net it out: offerings today […]

That Exciting New Stuff? Yeah… Wait Till It Ships.

by Merv Adrian  |  July 13, 2013  |  3 Comments

A brief rant here: I am asked with great frequency how this RDBMS will hold off that big data play, how data warehouses will survive in a world where Hadoop exists, or whether Apple is done now that Android is doing well. There is a fundamental fallacy implicit in these questions. Comparing what someone new […]

Hadoop Summit Recap Part One – A Ripping YARN

by Merv Adrian  |  July 10, 2013  |  7 Comments

I had the privilege of keynoting this year’s Hadoop Summit, so I may be a bit prejudiced when I say the event confirmed my assertion that we have arrived at a turning point in Hadoop’s maturation. The large number of attendees (2500, a solid increase – and more “suits”) and sponsors (70, also a significant uptick) made […]

Hadoop 2013 – Part Four: Players

by Merv Adrian  |  March 8, 2013  |  1 Comment

The first three posts in this series talked about performance,  projects and platforms as key themes in what is beginning to feel like a  watershed year for Hadoop. All three are reflected in the surprising emergence of a number of new players on the scene, as well as some new offerings from additional ones, which I’ll cover in […]

Hadoop 2013 – Part Two: Projects

by Merv Adrian  |  February 21, 2013  |  1 Comment

In Part One of this series, I pointed out that how significant attention is being lavished on performance in 2013. In this installment, the topic is projects, which are proliferating precipitously. One of my most frequent client inquiries is “which of these pieces make Hadoop?” As recently as a year ago, the question was pretty simple for […]

Hadoop 2013 – Part One: Performance

by Merv Adrian  |  February 16, 2013  |  11 Comments

It’s no surprise that we’ve been treated to many year-end lists and predictions for Hadoop (and everything else IT) in 2013. I’ve never been that much of a fan of those exercises, but I’ve been asked so much lately that I’ve succumbed. Herewith, the first of a series of posts on what I see as […]
