The Hadoop Online Tutorials website features numerous free and paid online courses. Some are duplicates of the ones listed here, but there are many others, as well.
8. MapR Free Hadoop Online Training Courses
If you’ve been around the Big Data industry, you’ve already heard of MapR.

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.
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, Hortonworks, IBM, Microsoft, etc.
