Nice article, but I doubt I have the confidence to try this at home...

With Virtual Box and Ubuntu its pretty easy to get started with Linux.
Using the Cloudera image is also very easy.

If you cock it all you will lose is a bit of disk space until such time as you delete the virtual image. Well, maybe a couple of evenings as well!

The only reason I haven't got it running on my home PC is that I've got an ancient 32bit PC with 3GB RAM running Windows XP and cannot run the Cloudera versions after CDH3 and CDH4.1 onwards are the ones where you have a GUI to play with.

Have a look at the SQLBits website for Justin Langford's presentation on HDInsight. Again, its very easy to install this on a Windows box and get started. The idea is that you have a local instance even though it is just one node. It's good enough to try the mechanical bits and bobs even if you haven't got the benefit of the full map-reduce.

Okay - I'll try that when I have some free evenings.

Thanks David.

You might also want to take a look at Splunk. I've heard good things about its ability to analyze gigabytes of data quickly. http://www.splunk.com/?r=header

Great article, the first I've read that clearly and simply explains what Hadoop is. Thanks

Great article!! Do you think it is worth learning a little bit of Java for this?

i'm looking at this as well. i've had it with full text indexing for a security log analysis solution i built up over the years. looking at analysis services and hadoop.

playing with SSAS for now and will try hadoop later.

I enjoyed the article. Like others I have been in the Windows world for a very long time, and Linux is something of a new adventure for me. I just finished, with a lot of help from my friends, a RedHat 17 based NAS for my home network.

I am interested in the "WHAT" of Hadoop. As in what would it be used for in business? Would you or someone give some hard examples of uses?

Hi David, I attended Justin's talk at SQLBits, don't know if you were also there in person (a good introduction I thought).

I had a quick word with him at the end and asked if there were any good walkthroughs or practical exercises for HDInsight newbies and he recommended this by Cindy Gross: http://blogs.msdn.com/b/cindygross/archive/2013/01/31/mash-up-hive-sql-server-data-in-powerpivot-amp-power-view-hurricane-sandy-2012.aspx

I haven't had a chance to work through it yet but may well do soon, like yourself I've recently got a Linux installation up and running (Fedora) but suspect that the MS version will be a gentler learning curve to start off with.
