Description: The ResourceManager UI is a fundamental web tool for managing and monitoring resources in a cluster that uses YARN (Yet Another Resource Negotiator), a key component of the Hadoop ecosystem. This interface allows administrators and users to view in real-time the status of cluster resources, including memory usage, CPU, and other critical resources. Through this interface, one can observe running applications, their states, and the amount of resources they are consuming. Additionally, it provides detailed information about the cluster nodes, allowing for quick identification of any issues or inefficiencies. The interface is intuitive and designed for easy navigation, offering graphs and tables that summarize information clearly. This not only aids in daily operational management but is also essential for capacity planning and performance optimization of the cluster. In summary, the ResourceManager UI is an indispensable tool for any organization using Hadoop and YARN, as it provides visibility and control over system resources, thereby enhancing efficiency and effectiveness in processing large volumes of data.
