15 Free Hadoop Online Training Resources


Hadoop, an Apache open-source software framework for storing and crunching big data sets across clusters of machines, has hit the big time. Markets and Markets forecast in January 2017 that the Hadoop market could grow to more than $40 billion by 2021. Those forecasts are starting to look pessimistic, in fact, as global markets are forecast to improve steadily in 2018. A 2018 Forbes report projected that Hadoop and the big data market will grow to more than $99 billion by 2022 (representing a whopping 28.5% projected growth rate).

One thing remains certain: Growth on such an enormous scale creates an urgent need for lots more able-bodied IT pros to develop, manage and administer Hadoop implementations.

Given ample time and a penchant for the topic, many people in the field feel that you can learn what you need to know about Hadoop via self-study. For those folks, browsing the plethora of documentation on the Apache Hadoop website is a good starting point. You can also download the open-source Hadoop release, and take the opportunity to turn some knobs and explore Hadoop at your own pace.

Administrators and developers who prefer a more structured learning experience can take advantage of free online training courses designed to get you up to speed fast.
