What is Apache Hadoop and Where it is Used?

We are in the era of the data age, and there has been an abrupt increase in the size and scale of web data. Big data has distinct and complex unstructured formats.

This includes information from social media, websites, email and video presentations. Therefore, organisations need technologies to extract valuable intelligence from Big Data.

To process large data sets, there is a need to have technologies that can accurately and powerfully analyse the big data formats.

Google is one company that processes data using its Google File systems and MapReduce frameworks. These scalable frameworks motivated the Hadoop initiative. The Apache Hadoop allows the distributed processing of big data across many machines.

Apache Hadoop

Apache Hadoop is a powerful and scalable distributed computing platform that is widely used for storing, processing, and analyzing big data. Hadoop was created by Doug Cutting and Mike Cafarella in 2005, and it has since become an important tool for data scientists and analysts worldwide.

Apache Hadoop is a big data platform organisations use to manage and process large data sets. It helps perform various operations such as text analytics, structured and unstructured data analysis, machine learning, predictive modelling, and more. Apache Hadoop is popular for its high-performance processing capabilities for big data sets.

Hadoop is a programming language and framework that enables distributed data processing. It is written in Java and runs on the Linux system. It can process huge data sets and is designed to be simple, portable, and scalable.

Hadoop has several modules, like Hadoop Distributed File System (HDFS), MapReduce, etc. HDFS is the key element that connects the Hadoop framework with the operating system and provides the file system for storing the data. HDFS uses the block-level file system concept, which is very scalable.

Hadoop MapReduce is a framework that allows the execution of computations and provides fault tolerance. It works as the layer between the application programmes and the distributed storage mechanism. And finally, Hadoop’s Distributed Scheduler provides the job schedule, which plays an important role in the MapReduce framework.

Benefits of the Hadoop Framework

The popularity of the Hadoop application has grown significantly since it meets the needs of most organisations. The Hadoop framework provides flexible data analysis with an unmatched price-performance curve. The flexibility analysis feature applies to unstructured, semi-structured, and structured data.

The importance of the Hadoop framework has been recognised in places where massive server farms are used to collect data from many sources. It can process parallel questions as large, background jobs on one server farm.

The Hadoop ecosystem incorporates some tools to enable it to address specific needs. This includes description formats: Hive (a SQL dialect), Zookeeper (used for federating services), Oozie, Avro, Thrift, and Protobuf. Hadoop has many advantages since it can handle data from disparate systems regardless of the data’s native format. Sometimes data is stored in unrelated systems, but it is easy to dump it in the Hadoop cluster without applying a schema.

Hadoop is cost-effective as compared to other legacy systems. Keeping in mind that today there are large data sets, legacy systems are expensive since they were not engineered to cater to the large data sets. Hadoop is cheap because it relies on a redundant data structure. The framework is deployed on industry-standard servers, while other legacy systems are deployed on inexpensive specialised data storage systems.


The Hadoop framework has proven its efficiency in most organisations, but as much as it is fast and cost-efficient, legacy systems will be required to complement its use. The features of Hadoop will make the technology attractive.

Therefore, it is upon the organisations to take advantage of the framework. With Hadoop, organisations will make important predictions by sorting out and analysing large amounts of data. There is no doubt that Hadoop is the core platform for structuring big data sets.
