Description: The Hadoop command-line interface (CLI) is a fundamental tool that allows users to interact with the Hadoop ecosystem and its various components, such as HDFS (Hadoop Distributed File System) and MapReduce. Through the CLI, users can execute commands to manage data, perform analysis, and control the operation of Hadoop clusters. This interface is especially valued for its ability to provide detailed and direct control over operations, making it a preferred option for system administrators and developers. The Hadoop CLI allows tasks such as uploading and downloading files, executing MapReduce jobs, and managing permissions in the distributed file system. Its design is based on simplicity and efficiency, enabling users to execute commands quickly and effectively. Additionally, the CLI is extensible, meaning that new functionalities can be added as the Hadoop ecosystem evolves. In summary, the Hadoop CLI is a powerful tool that facilitates interaction with one of the most widely used data processing systems today, providing users with the flexibility and control needed to handle large volumes of information.
