10 Completely Free Resources for Sharpening Your Skills in Hadoop
Taking on a big data initiative isn’t cheap. If you have to add in Hadoop training costs for your entire IT and big data teams, the price tag can expand rapidly. Or, you can just take advantage of one of the numerous free resources available. Here are some options:
Most programs require payment to earn a degree or certification, but still offer a wide variety of their lessons and training for free.
There are about 80 different Big Data training courses at this online university, all for free. Learning paths include Data Science Foundations, Spark Fundamentals, Scala Programming for Data Science, Big Data Fundamentals, and (of course) Hadoop Fundamentals.
2. Hortonworks videos & tutorials
While most of Hortonworks’ courses require a fee, they also offer a number of tutorials, plus a number of helpful free videos on YouTube. To make the most out of the tutorials, download and install Hortonworks Sandbox. If you choose your training carefully, you can prepare to take the HDP Certified Developer exam without spending a dime, but the course to obtain certification is $250 USD.
3. Cloudera video courses
Cloudera also offers certification as a Cloudera Certified Associate in Spark and Hadoop. Their exam is $295 USD, but you can prepare online for free using their YouTube courses. Some of their free courses include Intro to Hadoop and MapReduce (offered via Udacity) and a live demonstration of Hadoop, Cloudera Live. They also have tutorials designed specifically for data analytics, administrators, and developers.
Another great place to look for courses is Udemy. While most of the offered courses come with a price tag, you can filter results by the term “free” and find a number of courses you might find useful.
5. Coursera video lectures
With online courses, it isn’t even necessary to take time off work to attend classes and study. If you’re offering classes for your employees, it’s a good idea to provide them time during the workday to complete their course work.
Coursera video courses make all of their video lectures and many of their training exercises available for free, though it is necessary to pay for a certification. These courses are developed with top universities like the University of California in San Diego, Stanford University, Duke University, and others. It’s a great foot-in-the-door program for those who are on the fence about pursuing a degree in data science or related disciplines.

Udacity makes their courses and materials available for free, but you’ll have to have a paid subscription to get a “degree” (called Nanodegrees). They feature an impressive list of free courses, including classes on data science, web development software engineering, mobile operating systems, and more. These courses are developed by industry superstars like Twitter and Facebook.
YouTube is an excellent training resource for everything from understanding big data use cases to learning how to program code. Just remember, the resource is only as good as the person or group putting it together. Check their credentials before opting into a YouTube course.
For many more generalized and specialized lessons and courses, browse YouTube. Just remember, it’s buyer beware, even when it’s a free course. Make sure you only spend time learning if you are certain that the “teacher” is a true data professional who’s in the know. Look for affiliations with known and trusted tech and data companies like Cloudera, IBM, Microsoft, etc.
In addition to these resources, you might also try IBM developerWorks, which offers free tutorials based on IBM technologies or the Hadoop Users LinkedIn Group, where you will likely find other training resources recommended by members of the group.
