Strata Spark Tsunami – Hadoop World, Part One

by Merv Adrian  |  October 31, 2014  |  3 Comments

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.

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.

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.

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.
