trait SchedulerExtensionService extends AnyRef

An extension service that can be loaded into a Spark YARN scheduler. A Service that can be started and stopped.

1. For implementations to be loadable by SchedulerExtensionServices, they must provide an empty constructor. 2. The stop() operation MUST be idempotent, and succeed even if start() was never invoked.
