Technology keeps changing and data keeps mounting where it is an ever-expanding field. Data soon becomes Big Data, manages voluminous chink of piling data which is more complex to store. In the present day, Big Data Hadoop is one of the most progressing technological fields. Just like the changes in the trends of the world, many changes have been made in the different fields of technologies. Hadoop is one among the newly developed technologies which has been pacing towards progress in the field of data handling. 

In the event of data handling, Hadoop has attained wide reorganization around the world owing to its highly successful factors. The reason is that many top multinational companies are showing keen interest in investing higher amounts in this technology. Over the span of a few years, enormous usage of data has progressed and there have been a lot of issues that are the resulting outcomes of this enormous data usage. There have been many complex issues like failures in effective processing of data, inability to store massive amounts of data and also the inability of effective handling of data.

For solving the issues that arise in the context of enormous data flow, Hadoop technology is the best solution. It uses the best techniques to facilitate the controlled flow of data for successful storing of the huge amount of data that is being in use in our day to day life.

What is big data?

Big data refers to enormous data, both structured and unstructured that’s beyond the processing capabilities of traditional data processing systems. The data escalates in ever-increasing volumes with a high velocity. The hadoop online training helps you to analyze for insights that can promote data-driven business decisions. 


A huge amount of data is generated every day from various sources that include IoT, businesses, social media and digital devices. To identify and deliver meaningful insights this data has been processed.


Every enterprise/organisation should process the huge volume of data within a specified time frame. While some processed and analyzed as the need arises, some data demands real-time processing capabilities.


Data has been generated from many sources where it is highly diverse and varied. In the relational databases, the traditional data type was mostly structured and fit well where Big Data comes in semi-structured and unstructured data types. (Like audio, video and text as well).

Hadoop Tutorial for beginners:

There were three core challenges when talking about Big Data.


The first issue is where to store such enormous amounts of data. Traditional systems offer limited storage capacities as they won’t have enough space to store such an enormous amount of data.

Heterogeneous data: The big data is highly varied; the question is that how to store this data that comes in diverse formats?

Processing speed:

The final issue is the processing speed. Big data comes in an enormous amount, it was a challenge to speed up the processing time of such heterogeneous data.

Hadoop was developed to overcome these core challenges. There were two primary components in Hadoop – HDFS and YARN. Both were designed to tackle the storage and processing issues. HDFS stores the data in a distributed manner and solves the storage issue, while YARN drastically handles the data and reduces the processing time. 

Hadoop is a unique Big Data Framework:

  • It eliminates ETL bottlenecks that feature a flexible file-system
  • It deploys on commodity hardware and can scale economically
  • It is not constrained by a single schema where it offers the flexibility to store and mine any type of data.
  • Its scale-out architecture divides workloads across many nodes where it excels at processing complex datasets.

Core components of Hadoop:

There are two primary components

  1. HDFS (Hadoop Distributed File System)
  2. YARN (Yet Another Resource Negotiator).


HDFS features a Master-Slave topology where it is responsible for distributed storage. In the Hadoop architecture, Master is a high-end machine that is deployed on robust configuration hardware as it constitutes the centre of the Hadoop cluster.

HDFS divides Big Data and then stores it in a distributed fashion on the cluster of slave nodes. Master is responsible to Manage, Maintain and monitor the slaves. The slaves function as the actual worker nodes. On a Hadoop cluster, the task is to be performed by connecting with the Master node.


YARN is responsible for data processing in Hadoop. The idea behind YARN is to split the task and schedule the job.
