Types

type Call 

type Call struct {
	// Identifies who generated this call. Master assigns a framework id
	// when a new scheduler subscribes for the first time. Once assigned,
	// the scheduler must set the 'framework_id' here and within its
	// FrameworkInfo (in any further 'Subscribe' calls). This allows the
	// master to identify a scheduler correctly across disconnections,
	// failovers, etc.

type Call_Accept

	XXX_unrecognized []byte                   `json:"-"`
}

Accepts an offer, performing the specified operations in a sequential manner.

E.g. Launch a task with a newly reserved persistent volume: 

Accept {
  offer_ids: [ ... ]
  operations: [
    { type: RESERVE,
      reserve: { resources: [ disk(role):2 ] } }
    { type: CREATE,
      create: { volumes: [ disk(role):1+persistence ] } }
    { type: LAUNCH,
      launch: { task_infos ... disk(role):1;disk(role):1+persistence } }
  ]
}

Note that any of the offer’s resources not used in the 'Accept' call (e.g., to launch a task) are considered unused and might be reoffered to other frameworks. In other words, the same OfferID cannot be used in more than one 'Accept' call.

	XXX_unrecognized []byte            `json:"-"`
}

Kills a specific task. If the scheduler has a custom executor, the kill is forwarded to the executor and it is up to the executor to kill the task and send a TASK_KILLED (or TASK_FAILED) update. Note that Mesos releases the resources for a task once it receives a terminal update (See TaskState in v1/mesos.proto) for it. If the task is unknown to the master, a TASK_LOST update is generated.

If a task within a task group is killed before the group is delivered to the executor, all tasks in the task group are killed. When a task group has been delivered to the executor, it is up to the executor to decide how to deal with the kill. Note The default Mesos executor will currently kill all the tasks in the task group if it gets a kill for any task.

}

Allows the scheduler to query the status for non-terminal tasks. This causes the master to send back the latest task status for each task in 'tasks', if possible. Tasks that are no longer known will result in a TASK_LOST update. If 'statuses' is empty, then the master will send the latest status for each task currently known.

}

Requests a specific set of resources from Mesos's allocator. If the allocator has support for this, corresponding offers will be sent asynchronously via the OFFERS event(s).

NOTE: The built-in hierarchical allocator doesn't have support for this call and hence simply ignores it.

	XXX_unrecognized []byte            `json:"-"`
}

Shuts down a custom executor. When the executor gets a shutdown event, it is expected to kill all its tasks (and send TASK_KILLED updates) and terminate. If the executor doesn’t terminate within a certain timeout (configurable via '--executor_shutdown_grace_period' agent flag), the agent will forcefully destroy the container (executor and its tasks) and transition its active tasks to TASK_LOST.

An event is described using the standard protocol buffer "union" trick, see: https://developers.google.com/protocol-buffers/docs/techniques#union.

	XXX_unrecognized []byte            `json:"-"`
}

Received when an agent is removed from the cluster (e.g., failed health checks) or when an executor is terminated. Note that, this event coincides with receipt of terminal UPDATE events for any active tasks belonging to the agent or executor and receipt of 'Rescind' events for any outstanding offers belonging to the agent. Note that there is no guaranteed order between the 'Failure', 'Update' and 'Rescind' events when an agent or executor is removed. TODO(vinod): Consider splitting the lost agent and terminated executor into separate events and ensure it's reliably generated.

}

Received whenever there are resources requested back from the scheduler. Each inverse offer specifies the agent, and optionally specific resources. Accepting or Declining an inverse offer informs the allocator of the scheduler's ability to release the specified resources without violating an SLA. If no resources are specified then all resources on the agent are requested to be released.

}

Received when a custom message generated by the executor is forwarded by the master. Note that this message is not interpreted by Mesos and is only forwarded (without reliability guarantees) to the scheduler. It is up to the executor to retry if the message is dropped for any reason.

}

Received whenever there is a status update that is generated by the executor or agent or master. Status updates should be used by executors to reliably communicate the status of the tasks that they manage. It is crucial that a terminal update (see TaskState in v1/mesos.proto) is sent by the executor as soon as the task terminates, in order for Mesos to release the resources allocated to the task. It is also the responsibility of the scheduler to explicitly acknowledge the receipt of a status update. See 'Acknowledge' in the 'Call' section below for the semantics.
