How to Become a Hadoop Developer?

What is Hadoop?

Hadoop, an open-source framework, is a digital behemoth designed for managing and analyzing vast amounts of data that overwhelm standard systems. Its core comprises the Hadoop Distributed File System (HDFS) for data distribution, ensuring redundancy, and fault tolerance; and MapReduce, a task-dividing programming approach for efficient data processing across a cluster. With scalability and orchestration, Hadoop empowers organizations to gain insights, make informed decisions, and innovate in today's data-rich landscape.
