The Java.net website polled its readers over the last 3 weeks about how much they knew about Hadoop.  Out of the 1567 responses, a whopping 70% said that they already had a “pretty in-depth knowledge” of Hadoop, which is the most expert-level response choice on the poll.  Here are the full results.

The site editor admits the poll was not necessarily done in a scientific manner.  Nevertheless, the 70% is very surprising to me.  How many of your Java programmer friends would you say already have an “in-depth” knowledge of Hadoop?  As many as three out of four of your friends and colleagues?  How would you rate yourself on this poll?

I use Hadoop for data analysis every day.  I would be happy to share with you my collection of ideas on how to learn Hadoop and get practical hands-on experience quickly so that you can be more effective in your career.  Look on HadoopWizard.com for information on Hadoop training classes, conferences, books, videos, tutorials and certification programs.

For now, look for a training event near where you live on our Master Training Calendar.
