Hadoop: First Steps

I think you’ll be interested in this link.

http://hadoop.apache.org/

“The Apache™ Hadoop™ project develops open-source software for reliable, scalable, distributed computing.

The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures.”

 

I know, that’s a little bit dense. Let’s see if we can’t break it down a little bit.

The first thing to know is that Apache Hadoop is program designed to aid in the use of distributed computing. Unsurprisingly, it is published by the Apache Software Foundation. It was developed by a very google-able man named Doug Cutting.

Hadoop allows a multitude of computers to be used within a network to accomplish large amounts data processing within a short period of time.

Let me give you an example.

Years ago I worked for the Department of Physics and Astronomy at the University of KY.  One of the goals of the department was to aid the SETI project.  SETI stands for Search For Extraterrestrial Intelligence.  Those who have seen the movie Contact (or the excellent novel by Carl Sagan that it is based off of)  may be familiar with the notion that the search for intelligent life outside of Earth involves the sifting through of enormous, gigantic amounts of noise in the search for patterns.  The SETI program, never a favorite in Washington, could not afford the immense computing power required to process the signals it received from places like the VLA.

Because of this, distributed computing programs were developed that would utilize the combined processing power of many computers all over the world.  Any time a computer that was part of the distribution network entered a period of user inactivity it would take that time to download a data packet from the SETI headquarters and process the packet for patterns that would indicate some manner of regularity.  It would then send its findings back to a host computer.

Now, the program used back then was called SETI@Home and it was rather primitive compared to what is available now.  Hadoop does not require the computers within the network to be idle, and it doesn’t necessarily rely on single packets of information to be downloaded to each computer.  It’s much more flexible than that. Read more about how exactly Hadoop works at the official Apache site:

http://hadoop.apache.org/

While you’re on the site be sure to have a look at the companies featured in the “Who uses Hadoop?” section.  Some very big names in there.  Amazon, Bing, Yahoo, Facebook.  The list goes on.

Next time we’ll have a look at Google’s MapReduce in relation to Hadoop, and what sort of projects that you might be able to undertake with them.

Zettabyte’s Stance On SOPA

I would like to talk a moment to talk about a very important issue on behalf of myself and Zettabyte Systems, LLC.

Right now there is a bill before congress called the Stop Online Piracy Act (SOPA). The principle purpose of this bill is to protect the intellectual properties of companies in the entertainment industry, that produce media in the form of films, television shows, music, and video games. In the event that this bill passes in congress, it will have some very serious ramifications for the future of the Internet, as we currently know it.

In theory the protection of intellectual properties, or IP, is a good thing. Zettabyte is in agreement that the intellectual properties of major labels like Fox, Universal, or NBC should be protected. There are thousands of people active every day in the industry to produce products for consumers that deserve to get paid for their hard work. It is a disservice for them not to have some measure of security and promise by the government to protect their work from being distributed in a manner that denies them what they have earned.

However, this bill is not the way.

If SOPA is passed it will grant unfair censorship powers to the United States government that could fundamentally alter the structure of the Internet as we know it today. Single instances of copyright violation could be used as rationale to perform unreasonable shut-downs of any site that government sees fit. Simple things like a Youtube video featuring an unlicensed clip of a song owned by a major record label, or the use of forum avatars featuring copyrighted material could be used as sufficient evidence of pirate activity. This is not protecting the rights of artists, this is simple censorship of creativity.

Companies and websites like Facebook, Youtube, and Twitter have all made statements condemning SOPA. In fact, nearly every major company in the tech industry has expressed opposition to the bill as it stands.

To learn more about SOPA, and exactly what it is I encourage you to visit this link:

You can read the SOPA bill in it’s entirety here:

Congress has postponed voting on SOPA until early 2012. There is still time to make a difference. You can read about the upcoming vote here:

TL;DR:

Zettabyte Systems officially opposes SOPA.
