free online courses to learn big data

If you are thinking of learning big data and starting your big data journey and looking for great free resources such as books, tutorials, courses, you are in the right place.

This article will share some of the best free online big data courses for Java, Scala, and Python developers. If you are not sure what Apache Spark (big data) is, let us start with a quick overview of why it is so important in the big data world.

Apache Spark is another cluster computing framework like Hadoop used to analyze large datasets. Still, it’s much faster than Hadoop, so today’s sophistication, such as processing large amounts of data Ideal for various computing needs.

One of the challenges when working with large amounts of data is speed, as it can take hours or days to train machine-learning algorithms using real-world data.

If you run, a comparison to the memory calculates the Hadoop 100 times, from the disk Map Reduce when running 10-fold speed it will provide.

These free Apache courses only teach basic concepts such as why you need Apache Spark What if you have Hadoop. Alternatively, learn how Apache Spark gets the lighting speed, and major Apache Spark abstractions such as Resilient Distributed Dataset and RDD.

By the way, if you’re willing to spend a few dollars learning valuable skills like big data, Spark, Hadoop, etc., I highly recommend checking out Apache Spark with Scala — Hands-on with Big Data as well. Of course to Frank Kane Udemy.

It is also not very expensive and can be purchase for just $ 9.9 for the occasional Crazy Udemy sale.
