Hadoop is an open-source framework that stores and process big data in a distributed environment using simple programming models. It is designed to scale up from single servers to thousands of machines, while each offers local computation and storage. Hadoop divides a file into blocks and stores across a cluster of machines. It achieves fault tolerance by replicating the blocks on a cluster.
Hadoop can be used as a flexible and easy way for the distributed processing of large enterprise data sets. Apart from humongous data, it includes structured, semi-structured, and unstructured data including Internet clickstreams records, web server, social media posts, customer emails, mobile application logs, and sensor data from the Internet of Things (IoT). In brief, Big data is made simple with Hadoop. So, Hadoop professionals get hired everywhere. It is an in-demand job these days.
To sustain in the cut-throat competition, Hadoop certifications help you sustain in the market. Big companies like TCS, Wipro, Cognizant, and more are employing professionals who have earned certifications.
