If you are learning big data, want to explore Hadoop framework, and are looking for some awesome courses, then you have come to the right place! In this article, I am going to share some of the best Hadoop courses to learn Hadoop in depth. In the last couple of articles, I have shared some big data and Apache Spark resources that have been well-received by my readers. After that, a couple of my readers emailed me and asked about some Hadoop resources, e.g. books, tutorials, and courses, that they can use to learn Hadoop better. This is the first article in a series on Hadoop. I am going to share a lot more about Hadoop and some excellent resources in coming the month, e.g. books and tutorials. BTW, If you don't know, Hadoop is an open-source distributed computing framework for analyzing big data, and it's been around for some time.

The classic MapReduce pattern that many companies use to process and analyze big data also runs on the Hadoop cluster. The idea of Hadoop is simple: to leverage a network of computers to process a huge amount of data by distributing them to each node and later combining individual outputs to produce the result.

Though MapReduce is one of the most popular Hadoop features, the Hadoop ecosystem is much more than that. You have HDFS, Yarn, Pig, Hive, Kafka, HBase, Spark, Knox, Ranger, Ambari, ZooKeeper, and many other big data technologies.

BTW, why Hadoop? Why you should learn Hadoop? Well, it is one of the most popular skills in the IT industry today. The average salary for a big data developer in the US is around $112,000 and goes up to an average of $160,000 in San Fransisco, as per Indeed.

There are also a lot of exciting and rewarding opportunities in the big data world and these courses will help you understand those technologies and improve your understanding of the overall Hadoop ecosystem.

Without further ado, here is my list of some of the best Hadoop courses you can take online to learn and master Hadoop.

1. The Ultimate Hands-On Hadoop Course: Tame Your Big Data!

This is the ultimate course on learning Hadoop and other big data technologies, as it covers Hadoop, MapReduce, HDFS, Spark, Hive, Pig, HBase, MongoDB, Cassandra, Flume, etc.

In this course, you will learn to design distributed systems that manage a huge amount of data using Hadoop and related technologies.

You will not only learn how to use Pig and Spark to create scripts to process data on Hadoop clusters but also how to analyze non-relational data using HBase, Cassandra, and MongoDB.

It will also teach you how to choose an appropriate data storage technology for your application and how to publish data to your Hadoop cluster using high-speed messaging solutions like Apache Kafka, Sqoop, and Flume.

You will also learn about analyzing relational data using Hive and MySQL and query data interactively using Drill, Phoenix, and Presto.

In total, it covers over 25 technologies to provide you a complete knowledge of the big data space.

2. The Building Blocks of Hadoop Course: HDFS, MapReduce, and YARN

Processing billions of records is not easy — you need to have a deep understanding of distributed computing and underlying architecture to keep things under control. And if you are using Hadoop to do that job, then this course will teach you all the things you need to know.

As the name suggests, this course focuses on the building blocks of the Hadoop framework, i.e. HDFS for storage, MapReduce for processing, and YARN for cluster management.

In this course, you will learn about Hadoop architecture and then do some hands-on work by setting up a pseudo-distributed Hadoop environment.

You will submit and monitor tasks in that environment and slowly learn how to make configuration choices for the stability, optimization, and scheduling of your distributed system.

At the end of this course, you should have a complete knowledge of how Hadoop works and its individual building blocks, i.e. HDFS, MapReduce, and YARN.

3. SQL on Hadoop: Analyzing Big Data With Hive

If you don't what Hive is, let me give you a brief overview. Apache Hive is a data warehouse project build on top of Apache Hadoop for providing data summaries, queries, and analyses. It provides a SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop and NoSQL databases like HBase and Cassandra.

This course starts with explaining key Apache Hadoop concepts like distributed computing and MapReduce and then goes into great detail into Apache Hive.

The course presents some real-world challenges to demonstrate how Hive makes tasks easier to accomplish. In short, this is a good course to learn how to use the Hive query language to find solutions to common big data problems.

4. Big Data and Hadoop for Beginners (Hands-On!)

If you are a beginner who wants to learn everything about Hadoop and related technologies, then this is the perfect course for you.

In this course, instructor Andalib Ansari will teach you the complex architecture of Hadoop and its various components like MapReduce, YARN, Hive, and Pig for analyzing big datasets.

You will not only understand what the purpose of Hadoop is and how it works but also how to install Hadoop on your machine and learn to write your own code in Hive and Pig to process a huge amount of data.

Apart from basic stuff, you will also learn advanced concepts like designing your own data pipeline using Pig and Hive.

The course also gives you an opportunity to practice with big datasets. It is also one of the most popular Hadoop course son Udemy with over 24,805 students already enrolled and over 1,000 ratings at an average of 4.2.

5. Learn Big Data: The Hadoop Ecosystem Masterclass

This is another great course to learn big data from Udemy. In this course, instructor Edward Viaene will teach you how to process big data using batch processing.

The course is very hands-on but comes with a good amount of theory. It contains more than six hours of lectures to teach you everything you need to know about Hadoop.

You will also learn how to install and configure Hortonworks Data Platform (HDP). It provides demons that you can try out on your machine by setting up a Hadoop cluster on the virtual machine (though you need 8GB+ RAM for that).

Overall, this is a good course for anyone who is interested in how big data works and what technologies are involved, with some hands-on experience.

Conclusion

That's all for some of the best courses to learn Hadoop and related technologies like Hive, HDFS, MapReduce, YARN, Pig, etc. Hadoop is one of the most popular frameworks in the big data space and a good knowledge of Hadoop will go a long way in boosting your career prospects, especially if you are interested in big data.
