Top 5 Free Big Data Courses for Java Programmers in 2022 to Learn Hadoop, Spark, and Kafka - Best of Lot

Hello Java Programmers, If you want to learn Big Data technologies in 2022 like Hadoop, Apache Spark, and Apache Kafka and you are looking for some free resources like books, courses, and tutorials, then you have come to the right place. This article will share some of the best free online practices to learn Hadoop and Spark from Udemy and Pluralsight at your own pace. I like to start with FREE resources before I have enough knowledge to choose the right book or enroll in a little expensive course. It's also my passion to surf the web to find great free resources and share them with you guys.

Like Data Science, Big Data is another space that I am looking to learn better in 2022. There are a lot of tools, technology, frameworks, and libraries that exist in the Big Data space. Still, I have chosen the one closer to the Java community like Apache Hadoop, Spark, and Apache Kafka.

Since Big Data is not limited to Java, I have included a free Scala course on Apache Spark. If you are a Scala developer or learning Scala to become a Polyglot programmer, which itself is an excellent idea.

If you are new here, you may want to check out some more free courses on Java, Spring, Linux, Python, SQL, Angular, React, Oracle, Eclipse, Maven, and several other Java and related technologies.

Also, If you are serious about learning Big Data and don't mind spending a few bucks on good learning resources, then you can also check out The Ultimate Hands-On Hadoop - Tame your Big Data! By Frank Kane on Udemy. This is one of the best and most comprehensive online courses to learn Big Data and Hadoop at this moment.





5 Free Online Courses to learn Big Data and Hadoop in 2022

Without wasting any more of your time, here is my list of some of the best free online courses to learn about Big Data and Hadoop in 2022. It also includes lessons on Apache Spark, another exciting Big Data framework that works well with Java, Scala, and Python.

These are some of the best free Big Data Courses from Udemy and Pluralsight to kick-start your journey into the beautiful world of Big Data in 2022:




    1. Hadoop Starter Kit [Free course Udemy]

    If you don't know, Apache Hadoop is the leading Big Data framework that provides utilities that facilitate using multiple computers to solve problems involving massive data like Google Search. It's based on Map Reduce pattern i.e. you can divide a Big Problem into several small ones and then combine the result from each node to produce the final result.

    This is a great course to learn about Hadoop. It explains all core concepts of Hadoop in fun and easy ways like HDFS, Map Reduce, Apache Pig and Hive, etc.

    If you are passionate about Big Data and Hadoop, this is a great course. It's free, and you also get access to a multi-node Hadoop training cluster to practice along the course.

    You will also learn to calculate the maximum closing price for stock symbols from a stock dataset using Apache Pig and Hive. Overall, a fantastic, hands-on course to learn about Hadoop.

    Suppose you are thinking of learning Apache Spark, another great Big Data framework that provides better throughput than Hadoop in many cases with Scala Programming language. In that case, this is a great course to start with.

    This course will teach you how to set up your development environment for building a Spark application using Scala with IntelliJIDEA.

    It comes with a Scala plugin which makes developing the Scala application really easy. You will also run how to integrate Spark within IntelliJ IDEA.

    Even if you are new to Java and Scala world, you can take this course because it will guide you step by step from installing Java, IntelliJIDEA, to Apache Spark.

    In short, a good introductory course on Apache Spark with Scala Programming language.






    3. Big Data and Hadoop Essentials [Free Udemy Course]

    This is one of the most popular free Big Data and Hadoop courses on Udemy, with over 80,000 students already enrolled in it. This speaks volumes about the quality of the course.

    In this course, you will develop an understanding of Big Data Problems with some real-world examples. You will learn about Hadoop and understand why it is so powerful.

    You will also understand the difference between Data Science and Big Data, which often confuses programmers while selecting a career path or understanding a job description.

    Even though this is a concise course, just 45 minutes long, you will learn enough about Big Data and Hadoop to start your journey. I highly recommend this course before you can take any other course on BigData and Hadoop.

    4. Learn BigData & Hadoop with Practical [Free Udemy Course]

    One of the main challenges to start with Big Data development is setting your own development environment. Since Big Data comprises many open source technologies like Hadoop, Spark, Pig, Hive, etc., it becomes complex to get an end-to-end environment.

    This free Big Data course will teach you how to set up a Big Data development environment on your personal computer or laptop using distributions like Cloudera or Hortonworks. This is a complete practical course on Big Data and Hadoop. 

    Both Cloudera and Hortonworks provide a virtual machine image containing all Big Data Eco System tools pre-packed, making it easy to start learning and doing development.

    You will also learn to set up other necessary components such as MySQL database and log generation tool and review all essential concepts like HDFS, Map Reduce, Pig, Hive, Spark, etc.

    5. Big Data: The Big Picture  [Free Trial Pluralsight]

    One of the mistakes many developers made while learning a new technology or programming language, including me, is directly going into details without understanding the Big Picture.

    If you know why something exists like the problem, you will better understand the technology and how it solves it.

    This course is just for that. It will tell you about concepts, companies, and technologies that make up the whole Big Data world and help you understand how you can adapt Big Data to solve your own business problem.

    The instructor Andrew Brust is ZDNet's Big Data correspondent and provides a different overview of Big Data than you will get from a Programmer or fellow developer.

    That's all about some free courses to learn Big Data technologies like Hadoop and Apache Spark. You can take these courses in the comfort of your office or home. You can also learn at your own pace, no need to rush or go anywhere.

    Btw, In Udemy, a free course sometimes turns into a paid course, so make sure you check that before you join the course, but once you join these courses, you will get lifelong access to them free of cost.

    I generally join the course to get it free once it's available, even if I don't have enough time to attend that fully. I can always go back and learn once I enroll in that course.

    If you are interested in these courses better to enroll now than later when they may not be free.
