When you start learning something entirely new, you learn really fast depending upon several steps or levels of learning. It takes a few hours to hit the beginner’s level. From beginner to intermediate level, it takes days. And finally, from intermediate to expert level, it takes months. But learning never ends. You keep on learning the new things till your last breath. In this write-up, we are going to have a closer look at the best learning strategy to learn Hadoop quickly.
Who can learn Hadoop?
If you are planning to make your career in Hadoop, make sure you fulfill the following criteria. Hadoop can be done by: -
- Managers who are looking forward to implementing the latest technologies in their work environment.
- A graduate and postgraduate who is looking for an aspiring career in the high-end technologies of information technology.
- Software engineers who are int ETL/Programming and discovering great opportunities
What does it take to be a Hadoop expert?
The best learning strategy that we would like to expose here to learn Hadoop quickly is to follow the 3-step learning method of Hadoop.
Learning Strategy to learn Hadoop quickly
- Learning Java: - Start your Hadoop learning from Java. Java is the base of Big Data Hadoop. Though Java is a programming language and Hadoop is an open-source framework which is written in Java programming language. Hadoop framework can be coded in any language, but still, Java is preferred. For Hadoop, the knowledge of Core Java is sufficient, and it will take approximately 5-9 months.
- Learning Linux operating system: - It is recommended to have a basic understanding and working of the Linux operating system. Linux is used for the installation of Hadoop framework. If you have the prior understanding of Linux, then it would be easier for you to install the Hadoop framework in a few steps. For this, mark at least a month.
- Learning Database: - Fundamental knowledge of SQL is a must for learning Hadoop. You must be experienced with SQL commands and queries because Hadoop grasps and processes a large amount of data and various components of the Hadoop ecosystem.
Summary of the learning objectives
- You should know your purpose of learning Hadoop very well
- Know about Hadoop’s popularity, its need in the market and scope, and then begin your learning
- Hadoop is a vast area, so try to learn about its various components, their applications
- It is always healthy to refer some books for learning, and so, in this case, you may also refer several books like Hadoop for dummies, Hadoop- a definitive Guide and many more books
- Follow popular blog writers of Hadoop, so that you will get updates in the technology in proper time
- Your ultimate goal behind learning Hadoop is to get placed in the Hadoop industry, and for that, I would suggest you take certification courses that will help you in mastering Hadoop and also will provide you a better direction or guidance in the field
Step 0: Programming skills
- Python It is a high-level programming language which is used to create web-server applications. Although Python is not at all tough to learn or time taking.
- Scala It is a general-purpose programming language which combines object-oriented and functional programming in one concise. It is designed to be concise. The difficulty level of learning Scala is medium.
- Java It is also a general-purpose programming language which is based upon the concepts of class and objects and has a few implementation dependencies as much as possible.
- C++ Learning C++ is really the fundamental base of any of the programming language because of the object-oriented concepts use in it.
Step 1: Database skills
- Relational Database It is a digital database which is used to manage database systems visually. It makes use of SQL.
- MongoDB (or NoSQL) It is a cross-platform to manage object-oriented database program.
Step 2: Analytical skills
- Problem-Solving Big Data Hadoop surrounds problem-solving, you need to be easy-going with this skill
- Statistics Hadoop involves calculations and mathematical skills for the analysis of data.
- Quantitate Analysis While working with Hadoop; you must also be working with exact data and figures.
Step 3: Cloud skills
- Google cloud platform Just to understand the working, to store, or to manipulate data on the cloud
Step 4: Data warehousing
- Hive Apache Hive is a data warehouse project built on the top of Apache Hadoop which provides analysis of SQL and Apache Hadoop for providing data query and analysis.
- PostgreSQL It is a DBMS tool used for emphasizing extensibility and technical standards compliance
- Apache Spark It provides an interface for entire programming clusters with implicit data parallelism and fault tolerance.
- MapReduce It is a programming model which is efficient in processing large volumes of data.
- HDFS Hadoop Distributed File System is used to run on commodity hardware. It is the primary storage system of Hadoop.
Based upon the platform, you choose to learn Hadoop
Self-Learning Platform for Hadoop
If you choose the self-learning method to learn Hadoop, then it will take approximately 3-4 months. Because you have to Google your queries every time and have to answer them on your own. You are your teacher.

Hadoop Training from Industry experts
If you opt for training as the majority of people do, then you can learn Hadoop in merely 2-3 months. You can take up a certificate-based training which can leverage your skills as well as a resume at the phenomenal rate.
Overall, what you will be doing in this time span of learning-
- A mixture of studying (different platforms)
- Understanding Hadoop
- Solving practical problems
- Implementation of Hadoop
Hadoop as your first technology or second
If you are planning to learn Hadoop as your first programming language, then think twice. Although there are no specific pre-requisites to learn Hadoop, still you must be proficient in Java, Linux, and SQL languages. So indirectly, Hadoop alone cannot be your first programming language. You need the fundamental knowledge of Object-Oriented Programming to ease your Hadoop learning.
In short, learning all the basic level languages (Java), Database concepts (SQL), operating system learning (Linux), practicing programming and the other concepts, Hadoop learning will take at least one year.
We do understand your zeal to learn Hadoop, that’s why we have made an effort to lessen your time span of learning Hadoop. You can join six weeks Hadoop training at JanBask Training to accomplish your dreams to become Data Scientist in a shorter period.

Read: Salary Structure of Big Data Hadoop Developer & Administrator
Casual Learners pick up the skills as time allows to them. They don’t rush what to learn. They just try out new things.
Career Advancers are the people who know that only skills are going to help them better. They know what to study and take one bite of cookie at a time.
Career hangers are the people who are passionate and goal-oriented. They do consistent learning. They’re more prominently focused on topics.
Out of the three learners, which learner you are?
The more time, the better do what you can! Give 5-15 hours a week to make yourself stand in the community of Hadoop. In the end, it depends upon your own learning pace. Do you want to run a race, a half marathon, or a full marathon? The urgency lies in the intensity of each of these goals on the necessity of an approach in timelines. The success lies in as soon as you want. Happy Learning!
