How Hadoop Changed the World through Big Data


The internet could achieve little if it wasn’t searchable, and a surprisingly unknown man named Doug Cutting is partly responsible for Google’s ability to return results with sub-second latency. In the late Nineties, Cutting created a full-text library that could build indexes capable of mapping search terms and their location in written prose. Three years later, he made Lucene open source, giving others the benefit of his library while encouraging feedback and inviting feature requests. Lucene soon became a part of Apache Software Foundation before Cutting decided to place more focus on indexing power in the hope that he might develop something capable of covering the internet in full.

Web crawlers were born and the PageRank algorithm became an important way to count links and determine page importance. After 2003, Cutting, Mike Cafarella, and Google’s efforts resulted in a framework that Yahoo ultimately transformed into Hadoop, which worked on a 1000 node cluster. Yahoo made its creation open source to the Apache Software Foundation, who raised Hadoop’s node cluster to 4000. Since then, Apache Hadoop has evolved into Version 2.0.6. Today it can index all types of big data, from structured to semi and unstructured databases.

The Evolution of Science and Enterprise

Hadoop has advanced at a rapid pace, and today, it can store and analyze big data robustly enough to support massive social networks including Facebook and Twitter. It’s equally adept at supporting scientific research, and its predictive analytics capabilities are rapidly improving well enough to give corporations real control over their information. This has changed the very fabric of the modern enterprise, giving businesses the capacity to assess any metrics related to any department, from marketing to human resources, even supporting predictive analytics. The investment industry has changed irrevocably, and every part of every industry in the world can now function in an evidence-based way, leaving rivals behind.

Data Science

The world of big data relies on the volume, variation, and speed of data rendering. The more it can process, the more powerful it becomes, and the adaptable Apache Hadoop method gives engineers a way to change their data frameworks based on their needs. This has altered the way IT merchants and data scientists live. Hadoop is used by almost all leading online brands because it’s potent and can be morphed into the precise product engineers need to support the businesses they serve. Hadoop has collaboration written into its history. Every growth spurt has happened thanks to the generosity of those who’ve been involved in its development. Open source programming has turned it into one of the most popular data storage structures in the world. It offers:

  • Computing power by processing enormous quantities of nodes
  • Versatility by storing data without requiring any processing in preparation. This is why it lends itself well to tools and languages like mapreduce and Python.
  • Speed by processing terabytes of data in mere minutes.
  • Adaptability by letting you decide how to handle defective nodes and analytics.
  • Economy by offering a free, open-source system.

Hadoop doesn’t function alone. It comes with Hadoop common—a group of libraries and tools that include file-based data structures and remote procedure calls to help with big data and Hadoop training. MapReduce is Hadoop’s distributing processing system, which can collect and separate data for parallel handling of conveyed datasets. Hadoop’s Distributed File System is a storage framework that can be spread across machines in a way that reduces costs. This way, data can be reused, compared, and written at an incredible velocity. YARN is an extra resource negotiator that controls distributed resources across devices. These tools are free, and as more and more professionals work with Hadoop, more tools emerge.

Big data might be a buzzword, but, in its raw form, it has little to offer. Much like letters you throw onto a page without thought, it’s only meaningful when it’s churned into relevant chunks. Hadoop doesn’t merely store and move big data. It lets you create small data that means something to you, and while it’s already caused a revolution, its open source presence will continue to revolutionize the way the world sees and treats information.
