Hadoop Is A Recursive Acronym

by Merv Adrian  |  October 13, 2014  |  2 Comments

Hopefully, that title got your attention. A recursive acronym – the term first appeared in the book Gödel, Escher, Bach: An Eternal Golden Braid and is likely more familiar to tech folks who know Gnu – is self-referential (as in “Gnu’s not Unix.”) So how did I conclude Hadoop, whose name origin we know, fits the definition?

Guest Post: Are You Pouring Pollution into the Data Lake?

by Merv Adrian  |  October 10, 2014  |  Comments Off

From my esteemed colleague Mark Beyer “Unstructured data” is a misnomer—everyone finally agrees on that much, at least. It is a term that is often applied to information assets that are not relational. Sometimes it is applied to machine data generated by operational technologies. Sometimes it is applied to content, like documents, or even less specific text […]

Satya Nadella at Symposium – What to Look For

by Merv Adrian  |  October 2, 2014  |  Comments Off

It’s rare that one gets the chance to talk to a new megavendor CEO in his first year on the job – especially in front of 10,000 senior IT professionals. But that is the opportunity Drue Reeves and I have on Tuesday, October 7 in Gartner’s Mastermind interview. What have we got in mind? Enterprise IT […]

Microsoft’s Portfolio – A Formidable Mix

by Merv Adrian  |  September 20, 2014  |  2 Comments

For the past few months, I’ve been Gartner’s Vendor Lead for Microsoft. For some 30 vendors, we assign a single analyst to act as a focal point for coordinating across the 1000 analysts we have when research covers that vendor. In Microsoft’s case, that has proven to be fascinating – we have some 3 dozen […]

by Merv Adrian  |  July 24, 2014  |  5 Comments

This week Teradata made two acquisitions – Revelytix and Hadapt – that enrich its already sophisticated big data portfolio, while HP made a $50M investment in, and joined the board of, Hortonworks. These moves continue the ongoing effort by leading players. 4 of […]

What Is Hadoop….Now?

by Merv Adrian  |  June 28, 2014  |  4 Comments

In February 2012, Gartner published How to Choose The Right Apache Hadoop Distribution (available to clients). At the time, the leading distributors were Cloudera, EMC (now Pivotal), Hortonworks (pre-GA), IBM, and MapR. These players all supported six Apache projects: HDFS, MapReduce, Pig, Hive, HBase, and Zookeeper. Things have changed. [updated June 29] We included Datastax (a distributor  of Apache Cassandra) […]

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 […]
