        The Hadoop YARN Container Executor is a native component responsible for managing the lifecycle of containers
        on individual nodes in a Hadoop YARN cluster. It launches, monitors, and terminates containers, ensuring that
        resources like CPU and memory are allocated according to the policies defined in the ResourceManager.
