An overview about Apache Hadoop

An open-source framework written in Java which allows users to store as much as terabytes or even petabytes of Big Data – both structured and un-structured – across a cluster of computers. The unique storage mechanism which uses a distributed file system (HDFS) to map data across any part of a cluster.


There are four main architectural features of Hadoop:

Hadoop Common

Hadoop Common
Hadoop Common is called the Core of Hadoop and is formed of the utilities and libraries which support the other Hadoop modules. The Core also contains numerous JAR archives needed to start Hadoop.
Hadoop Common
Hadoop MapReduce

Hadoop MapReduce

Hadoop MapReduce

This is the module which offers a key selling point of Hadoop, as it ensures scalability. When data is received by Hadoop it is executed over three different stages:

  • Map: This is when the data is converted to key-value pairs which are known as Tuples.
  • Shuffle: This is when the data is transferred from the Map stage to the Reduce stage.
  • Reduce: Once the tuples have been received, they are processed and turned into a new set of tuples which are then stored via HDFS.

Hadoop Distributed File System (HDFS)

Hadoop Distributed File System (HDFS)
This is the name given to the storage system used by Hadoop. It utilizes a master/slave set-up, where one primary machine controls a large number of other machines, making it possible to access big data quickly across the Hadoop clusters. By dividing the data into separate pieces, it stores them at speed on multiple nodes in one cluster.

Hadoop YARN

Hadoop YARN

Hadoop YARN
In simple terms, YARN is a clustering platform which aids in the management of resources and the scheduling of tasks. It makes it possible for multiple data processing engines to operate within a single platform. These might include real-time streaming, interactive SQL, data science and batch processing.



The structure of Hadoop means that it can scale horizontally, unlike traditional relational databases. This is because the data can be stored across a cluster of servers, from a single server to hundreds.


Faster data processing is made possible by the distributed file and powerful mapping offered by Hadoop.


Both your structured and unstructured data can be used to generate value by Hadoop. It can draw useful insights from sources such as social media, daily logs and emails.


The data stored by Hadoop is stored in replicate form across different servers in multiple locations, which increases reliability.

Advanced Data Analysis

When utilizing Hadoop, it becomes simple to store, manage and process large data sets, bringing effective data analysis in-house.
