I took this course to prepare for a master’s in Educational analysis. My background was a degree in early childhood education, so I only had experience with qualitative analysis. This course helped me prepare for the initial data science course in my program and I could “hit the ground running”.

Fanny L. 5 / 5 stars – January 2023


Great course if you’re trying to learn R programming, not so much if you want data visualization or data mining (since these are better with Python or Matplotlib). However, you will do GGplot2, which provides you with some data visualization that you may see in a normal data analyst’s line of work. And Kirill’s classes are always solid, so you won’t be sorry for taking this course.

Best Course for Apache Spark and Scala by Frank Kane

Apache Spark with Scala – Hands On with Big Data overview:

For those who want to explore the power of Apache Spark with Scala, Udemy offers Apache Spark With Scala Hands-On With Big Data. This course provides an in-depth look at working with Apache Spark and its components such as RDDs, DataFrames, streaming data applications, and machine learning algorithms. This is another highly rated Frank Kane course, but specifically focusing on Apache Spark, Hadoop, and Scala.


  • One of the only high-quality courses that teaches this stuff on Udemy.
  • GraphX, SparkSQL, DataFraming, and Machine learning are all covered in this course.
  • Notably hands-on executions like “Find the Most Popular Movie”, “Find the most popular superhero in a social chart,” and other types of highly relevant real-life data science exercises included in this course.


  • No Python and R, this is a purely Scala, Hadoop course. That being said, you’ll learn ML in this framework instead.
  • The course is rather short – while most of these courses run 20-30 hours, this one is only nine hours long, so you’re not getting as much in-depth knowledge.


Despite the cons of this course, Frank is a fantastic instructor, boasting many years of experience working at large multinational companies doing data science and machine learning.

What do his students say?

Great overview of Spark with a nice overview of Scala included. Great work. The explanation for the nuances between RDD’s, dataframes, and datasets was very helpful to me.

In my case, I am using Spark with Hadoop but not sure that will be covered in much depth in this course. In either case, I think I’ll have enough foundation from this course to hopefully get me set to interact with Hadoop (and Hive) as well from Spark. But, perhaps at least a brief intro to those concepts in this course would be helpful to folks in my situation as well (if not already included somewhere here).

R C. – 5 / 5 stars – December 2022

I think is quite complete the content that you can find in this course and the extra sections also have interesting info

Julio L. – 5 / 5 stars – January 2023


This is an easy one. If you’re looking to learn Spark + Hadoop w/ ML, take this course. If you already know it or don’t have any inclination to learn it, avoid this course. Frank Kane is a strong instructor with over a decade of experience in ML and data science. Ultimately, he won’t steer you wrong.
