Big Data Hadoop Tutorial for Beginners
Throughout the long term, the amount of data generated has increased by leaps and limits, which comes in all forms and formats and also at a very fast rate. Earlier, data was managed and handled manually, usually because it was limited data, but having said that, in the current situation, that is not the situation. Along with it, the following important question is how do we manage this Big Data? This is where the Big Data Hadoop tutorial for beginners becomes possibly the most important factor — a framework used to store, process, and analyze Big Data.
As the volume of data generated continuously increases, storing, processing, and analyzing it has become very challenging, commonly known as Big Data.
The blog’s goal is to give a basic idea of Big Data Hadoop tutorial for beginners to all IT aspirants. This article will provide you with sound information on Hadoop basics and its central components. You will also get to realize why individuals started using Hadoop, why it became so popular rapidly, and why there is a superb demand for Big Data Hadoop Certification.

To prepare these tutorials on Big Data for beginners, I took references from different books and prepared this delicate definitive aid for beginners in Hadoop. This tutorial will provide ideal guidance to help you in deciding your career as a Hadoop professional in the data management sector or why to pick Big Data Hadoop as the primary career decision.
Introduction to What is Hadoop in Big Data
Hadoop is an open-source Apache framework that was created to function with big data. The main goal of Hadoop in Big Data is data collection from various distributed sources, processing data, and managing resources to handle those data files.
Individuals are usually confused between the terms Hadoop and big data. Not many individuals use these terms interchangeably, but they should not be. The popular modules that each Hadoop professional should be familiar with either as a beginner or advanced user include – HDFS, YARN, MapReduce, and Common.
HDFS (Hadoop Distributed File System)
This centre module provides access to big data distributed across numerous clusters. With HDFS, Hadoop gains admittance to numerous file systems, too, as expected by the organizations.
Hadoop YARN
The Hadoop YARN module oversees resources and timetable positions across numerous clusters that store the data.
Hadoop MapReduce
MapReduce works similarly to Hadoop YARN, but it is designed to process large data sets.
Hadoop Common
This module contains a bunch of utilities that help three other modules. Some of the other Hadoop ecosystem components are Oozie, Sqoop, Spark, Hive, Pig, and so forth.
What isn’t Hadoop?
Let’s discuss what Big Data Hadoop tutorial for beginners is not so that related confusion with the terminology can be avoided rapidly.
- Hadoop is not Big Data – Individuals are usually confused between the terms Hadoop and big data. Barely any individuals use these terms interchangeably, but they should not be.
- Hardly any individuals consider Hadoop as an operating system or set of packaged software apps, but it is neither an operating system nor a bunch of packaged software apps.
- Hadoop is not a brand but rather an open-source framework that can be used by registered brands based on their prerequisites.
Importance of Learning Hadoop
What is the use of learning Big Data Hadoop Tutorial for beginners? Hadoop is considered one of the top platforms for business data processing and analysis, and the following are some of its significant benefits for a brilliant career ahead:
Scalable
Businesses can process and get actionable insights from petabytes of data.
Adaptable
To access numerous data sources and types.
Agility
Parallel processing and minimal development of data process substantial amounts of data with speed.
Adaptable
To help a variety of coding languages, including Python, Java, and C++.

Center Components of Hadoop Modules
In this section of the Apache Hadoop tutorial, we’ll have a “Detailed discussion on Hadoop Modules or Center components to give you valuable insights on the Hadoop framework and how it works with big data”
HDFS – Hadoop Distributed File System
This centre module provides access to big data distributed across numerous clusters of commodity servers. With HDFS, Hadoop gains admittance to numerous file systems too, and it can work with almost any file system. This is the primary necessity by organizations, so the Hadoop Framework became popular in a more limited period only. The functionality of the HDFS centre module makes it the heart of the Hadoop framework.
HDFS monitors files and how they are distributed or stored across the clusters. Data is further separated endlessly impedes the need to access wisely to avoid redundancy.
Hadoop YARN – Yet another Resource Navigator
YARN oversees resources and timetable positions across numerous clusters that store the data. The significant components of the module include Node Manager, Resource Manager, Application Master, and so on.
The “Resource Manager” assigns resources to the application. The “Node Manager” manages those resources on different machines like computer chips, network or memory, and so forth.
Hadoop MapReduce
MapReduce works similarly to Hadoop YARN, but it is designed to process large data sets. This is a technique to allow parallel processing on distributed servers. Before real data is processed, MapReduce converts large sets into smaller data chunks that are named “Tuples” in Hadoop.
“Tuples” are easy to understand and work on when compared to larger data files. When data processing is finished by MapReduce, then work is handed over to the HDFS module to process the final output. In brief, the goal of MapReduce is to separate large data files into smaller lumps that are easy to handle and process.
Here the word MAP means Maps, Tasks, and Functions. The “Map” process aims to format data into key-value pairs and assign them to different nodes. After this “reduce” function is carried out to reduce large data files into smaller lumps or “Tuples.” One of the important components of the MapReduce function is JobTracker which checks out how occupations are.
Hadoop Common
This module contains a bunch of utilities that help three other modules. Some of the other Hadoop ecosystem components are Oozie, Sqoop, Spark, Hive, Pig, and so on.
