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 [...]

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 [...]

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 [...]

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 [...]
