How to Learn Hadoop for Free

 hadoop logo

Big data is a buzzword that’s used a lot these days. If you’re wondering; what is big data? And what is the value of it? Well, to make a long story short; the idea of big data is to take huge clusters/chunks of unstructured and structured data (that are meaningless on their own) and converts them to meaningful sets of data. Hadoop is at the heart of big data, so what is Hadoop?

As defined by Apache; Apache Hadoop is an open source framework designed to enable the distributed processing of large data sets across clusters of commodity servers. What makes Hadoop framework special is its ability to scale up from a single server to thousands of machines, with a very high degree of fault tolerance. Rather than relying on high-end hardware, the resiliency of these clusters comes from the software’s ability to detect and handle failures at the application layer.

This post is a road map for anyone willing to start learning Hadoop online for free from scratch, the post will present and compare between the best online sources where beginners can start from and follow along, the sources stated in this post are full structured courses so you won’t find a link to a single video or a group of unrelated tutorials.

If you just want the bottom line (the road map to learn Hadoop) and you don’t wish to read the entire article then go to the “Bottom Line” section at the end of the article.
