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 [...]

Data Security for Hadoop – Add-on Choices Proliferating

by Merv Adrian  |  February 23, 2014  |  5 Comments

In my post about the BYOH market last October, I noted that increasing numbers of existing players are connecting their offerings to Apache Hadoop, even as upstarts enter their markets with a singular focus. And last month, I pointed out that Nick Heudecker and I detected a surprising lack of concern about security in a recent [...]

Microsoft’s New CEO – What’s Next for Microsoft?

by Merv Adrian  |  February 19, 2014  |  3 Comments

In the most profound change of leadership in Microsoft’s history, Satya Nadella, who was head of the Cloud and Enterprise division,  has taken the helm, succeeding Steve Ballmer. Nadella’s “insider” understanding of Microsoft’s culture and his effectiveness in cross-team communication and collaboration could help him reshape Microsoft for the digital era — which will be [...]

Security for Hadoop? Don’t Look Now…

by Merv Adrian  |  January 21, 2014  |  19 Comments

“Not looking” at security and privacy seems to be the posture of people implementing Hadoop, based on recent data Gartner has collected. This is troubling, and paradoxical. In an era when the privacy of data, from government surveillance to medical record-keeping to “creepy” marketing initiatives and password breaches, has been in the news regularly, it [...]

Aspirational Marketing and Enterprise Data Hubs

by Merv Adrian  |  January 17, 2014  |  3 Comments

In the Hadoop community there is a great deal of talk of late about its positioning as an Enterprise Data Hub. My description of this is “aspirational marketing;” it addresses the ambition its advocates have for how Hadoop will be used, when it realizes the vision of capabilities currently in early development. There’s nothing wrong [...]

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 [...]

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 [...]
