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 […]

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 […]

Open Source “Purity,” Hadoop, and Market Realities

by Merv Adrian  |  March 9, 2013  |  22 Comments

I don’t often do a pure opinion piece but I feel compelled to weigh in on a queston I’ve been asked several times since EMC released its Pivotal HD recently. The question is whether it is somehow inappropriate, even “evil,” for EMC to enter the market without having “enough” committers to open source Apache projects. […]

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 […]

Stack Up Hadoop to Find Its Place in Your Architecture

by Merv Adrian  |  January 30, 2013  |  8 Comments

2013 promises to be a banner year for Apache Hadoop, platform providers, related technologies – and analysts who try to sort it out. I’ve been wrestling with ways to make sense of it for Gartner clients bewildered by a new set of choices, and for them and myself, I’ve built a stack diagram that describes […]

Apache Hadoop 1.0 Doesn’t Clear Up Trunks and Branches Questions. Do Distributions?

by Merv Adrian  |  January 23, 2012  |  Comments Off

In early January 2012, the world of big data was treated to an interesting series of product releases, press announcements, and blog posts about Hadoop versions.  To begin with, we had the announcement of Apache version 1.0 at long last, in a press release. Although there were grumblings here and there in the twittersphere that […]
