Free Hadoop Introduction

Free Hadoop Introduction Highlights

In this Blog, we are going to talk about what is Hadoop, Evolution of Hadoop, Why organizations are using it, Hadoop architecture and Modules in brief.


Free Hadoop Introduction What is Hadoop

Let us understand what really Hadoop is.
It is an open-sourceJava-based programming framework, which helps in processing and storage of totally enormous data sets in a dispensed computing environment.
We can say in simple way like Hadoop Allows distributed processing of large datasets.
It provides enormous storage for any sort of information, huge processing and the capacity to control almost limitless concurrent duties or jobs.


Free Hadoop Introduction Evolution

Now, we will discuss the epitome of Hadoop evolution.
Apache Software Foundation designed Hadoop for reliable, scalable, distributed computing.
Hadoop was initially released in December 10, 2011 and stable version was released in August 25, 2016.


Free Hadoop Introduction Evolution

Let’s dive little deep to understand its evolution.
 The first version of Hadoop 1.0 had few components like Pig, Hive, Map Reduce and HDFS.
Later in Hadoop 2.0 version, which is now stable version, many components have been added, which are RT Stream Graph,Services HBase, Tez and YARN.


Free Hadoop Introduction Why Hadoop

Now, let’s understand where Hadoop is used?
Hadoop is quickly becoming a central store for big data in the enterprise.
A wide variety of companies and organizations use Hadoop for both research and production.
There are plenty of reasons, why companies or organizations require Hadoop.
Few of them are…
Hadoop supports Data Exploration with Full Datasets.
Hadoop can mine or sort the large datasets.
Hadoop Pre-process Large Scale Raw Data and for Data Agility.


Free Hadoop Introduction Hadoop modules

Let’s understand in brief about hadoop architecture and its modules.
Hadoop has four modules in its architecture, they are
Hadoop common.
Map Reduce.
The entire modules in Hadoop are designed with essential assumption that hardware failures are fashioned and should be automatically dealt with the aid of the framework.


Free Hadoop Introduction Hadoop Architecture

Let’s understand each in brief.
Starting with Hadoop common, it comprises libraries and utilities needed by different Hadoop modules.
While Hadoop distributed File process is a distributed file-method that stores information on commodity machines, providing very high aggregate bandwidth across the cluster.
Hadoop YARN is useful in resource-administration platform dependable for managing computing assets in clusters and utilizing them for scheduling of consumer’s applications.
And finally Hadoop Mapreduce, which is an implementation of the Map minimize programming mannequin for gigantic scale data processing.


Free Hadoop Introduction Key Features

Finally, let’s find out key features of Hadoop.
Hadoop offers many notable features, like
Hadoop Brings Flexibility in Data Processing, which is easily scalable. Also it provides fault tolerance which is handling bugs in code on its own. It offers excellent data processing speed and it has robust ecosystem. And above all, Hadoop is very cost effective, which makes it very popular.
