-/*
- * A dispatcher that is responsible for managing and launching drivers, and is intended to be
- * used for Mesos cluster mode. The dispatcher is a long-running process started by the user in
- * the cluster independently of Spark applications.
- * It contains a [[MesosRestServer]] that listens for requests to submit drivers and a
- * [[MesosClusterScheduler]] that processes these requests by negotiating with the Mesos master
- * for resources.
- *
- * A typical new driver lifecycle is the following:
- * - Driver submitted via spark-submit talking to the [[MesosRestServer]]
- * - [[MesosRestServer]] queues the driver request to [[MesosClusterScheduler]]
- * - [[MesosClusterScheduler]] gets resource offers and launches the drivers that are in queue
- *
- * This dispatcher supports both Mesos fine-grain or coarse-grain mode as the mode is configurable
- * per driver launched.
- * This class is needed since Mesos doesn't manage frameworks, so the dispatcher acts as
- * a daemon to launch drivers as Mesos frameworks upon request. The dispatcher is also started and
- * stopped by sbin/start-mesos-dispatcher and sbin/stop-mesos-dispatcher respectively.
