YarnNone

YarnNone is a configuration setting used in distributed computing frameworks like Apache Hadoop or Apache Spark. It indicates that no resource manager or container orchestration system (such as YARN) is responsible for managing and scheduling compute resources. Essentially, setting YarnNone means the application runs directly on the local machine or in an environment without a resource manager overseeing resources and job scheduling, which is often suitable for simple, small-scale, or testing tasks.
