by Merv Adrian  |  February 25, 2015  |  1 Comment

This is a joint post authored with Nick Heudecker There were many questions asked after the last quarterly Hadoop webinar, and Nick and I have picked a few that were asked several times to respond to here. Just to be clear, we don’t generally give deep advice in blog posts – our blogs are descriptive, not […]

Which SQL on Hadoop? Poll Still Says “Whatever” But DBMS Providers Gain

by Merv Adrian  |  February 22, 2015  |  1 Comment

Since Nick Heudecker and I began our quarterly Hadoop webinars, we have asked our audiences what they expected to do about SQL several times, first in January 2014. With 164 respondents in that survey, 32% said “we’ll use what our existing BI tool provider gives us,” reflecting the fact that most adopters seem not to want […]

Hortonworks IPO – Why Now?

by Merv Adrian  |  November 17, 2014  |  9 Comments

Last week, many observers were surprised when Hortonworks’ S-1 for an initial public offering (IPO) was filed. And there are good reasons to be surprised. Why now? CEO Rob Bearden told VentureWire not long ago that he expected to exit 2014 “at a strong $100 million run rate” in preparation for a 2015 IPO. What changed? […]

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 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 […]

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 […]
