Strata Spark Tsunami – Hadoop World, Part One

by Merv Adrian  |  October 31, 2014  |  10 Comments

New York’s Javits Center is a cavernous triumph of form over function. Giant empty spaces were everywhere at this year’s empty-though-sold-out Strata/Hadoop World, but the strangely-numbered, hard to find, typically inadequately-sized rooms were packed. Some redesign will be needed next year, because the event was huge in impact and demand will only grow. A few of […]

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 […]

Hadoop Distributions And Kids’ Soccer

by Merv Adrian  |  July 19, 2011  |  4 Comments

The big players are moving in for a piece of the Big Data action. IBM, EMC, and NetApp have stepped up their messaging, in part to prevent startup upstarts like Cloudera from cornering the Apache Hadoop distribution market. They are all elbowing one another to get closest to “pure Apache” while still “adding value.” Numerous […]
