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.
	FrameworkId *mesosproto.FrameworkID `protobuf:"bytes,1,opt,name=framework_id" json:"framework_id,omitempty"`
	// Type of the call, indicates which optional field below should be
	// present if that type has a nested message definition.
	Type             *Call_Type        `protobuf:"varint,2,req,name=type,enum=mesosproto.scheduler.Call_Type" json:"type,omitempty"`

* Scheduler call API.

Like Event, a Call is described using the standard protocol buffer "union" trick (see above).

type Call_Accept 

type Call_Accept struct {
	OfferIds         []*mesosproto.OfferID         `protobuf:"bytes,1,rep,name=offer_ids" json:"offer_ids,omitempty"`

	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.

}

Acknowledges the receipt of status update. Schedulers are responsible for explicitly acknowledging the receipt of status updates that have 'Update.status().uuid()' field set. Such status updates are retried by the slave until they are acknowledged by the scheduler.

}

Declines an offer, signaling the master to potentially reoffer the resources to a different framework. Note that this is same as sending an Accept call with no operations. See comments on top of 'Accept' for semantics.

	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 mesos.proto) for it. If the task is unknown to the master, a TASK_LOST update is generated.

}

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.

}

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' slave flag), the slave will forcefully destroy the container (executor and its tasks) and transition its active tasks to TASK_LOST.

Received when an invalid framework (e.g., unauthenticated, unauthorized) attempts to subscribe with the master. Error can also be received if scheduler sends invalid Calls (e.g., not properly initialized). TODO(vinod): Remove this once the old scheduler driver is no longer supported. With HTTP API all errors will be signaled via HTTP response codes.

}

Received when a slave 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 slave or executor and receipt of 'Rescind' events for any outstanding offers belonging to the slave. Note that there is no guaranteed order between the 'Failure', 'Update' and 'Rescind' events when a slave or executor is removed. TODO(vinod): Consider splitting the lost slave and terminated executor into separate events and ensure it's reliably generated.

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 are new resources that are offered to the scheduler or resources requested back from the scheduler. Each offer corresponds to a set of resources on a slave. Until the scheduler accepts or declines an offer the resources are considered allocated to the scheduler. Accepting or Declining an inverse offer informs the allocator of the scheduler's ability to release the resources without violating an SLA.

Received when a particular offer is no longer valid (e.g., the slave corresponding to the offer has been removed) and hence needs to be rescinded. Any future calls ('Accept' / 'Decline') made by the scheduler regarding this offer will be invalid.

}

Received whenever there is a status update that is generated by the executor or slave 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 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.
