Hadoop is a powerful open-source framework designed for the distributed storage and processing of large data sets across clusters of computers, making it a vital tool in the era of big data. Big data refers to vast volumes of data generated at high velocity and from various sources, presenting significant challenges in storage, analysis, and management. This paper outlines the installation steps necessary to set up a Hadoop environment on a Linux operating system, which provides a stable and efficient platform for running distributed applications. By offering a comprehensive overview of the installation and operational aspects of Hadoop, this research serves as a practical guide for beginners and practitioners, facilitating efficient data processing and enhancing the understanding of big data management in a Linux ecosystem.
