Description
YARN's core concept revolves around the division of resource management and job scheduling/monitoring into distinct daemons, aiming for a centralized ResourceManager (RM) alongside individual ApplicationMasters (AM) for each application. Each application can be defined as either a standalone job or a directed acyclic graph (DAG) of jobs. Together, the ResourceManager and NodeManager create the data-computation framework, with the ResourceManager serving as the primary authority that allocates resources across all applications in the environment. Meanwhile, the NodeManager acts as the local agent on each machine, overseeing containers and tracking their resource consumption, including CPU, memory, disk, and network usage, while also relaying this information back to the ResourceManager or Scheduler. The ApplicationMaster functions as a specialized library specific to its application, responsible for negotiating resources with the ResourceManager and coordinating with the NodeManager(s) to efficiently execute and oversee the execution of tasks, ensuring optimal resource utilization and job performance throughout the process. This separation allows for more scalable and efficient management in complex computing environments.
Description
Yarn serves as a dual-purpose tool, functioning both as a package manager and a project manager. It caters to a diverse range of users, from hobbyists to large enterprises, whether you're engaged in quick projects or comprehensive monorepos. With Yarn, you can compartmentalize your project into various sub-components within a single repository. One of its key features is the assurance that an installation that works today will continue to perform consistently in the future. While Yarn may not address every issue you face, it provides a solid base for further solutions. We are committed to redefining the developer experience and questioning conventional practices. As an independent open-source initiative, Yarn is not affiliated with any corporation, and your support is crucial to our success. Yarn has a comprehensive understanding of your dependency tree and takes care of installing it on your disk, so why should Node be responsible for locating your packages? Instead, it is the responsibility of the package manager to notify the interpreter about where the packages are stored on the disk and to handle any relationships and versioning between those packages. This shift in responsibility could enhance the overall efficiency of project management in development environments. Ultimately, Yarn aims to streamline the development process, making it easier for developers to focus on building great software.
