> Slave might want to kill revocable tasks based on correction events from the QoS controller.
> The QoS controller communicates corrections through a stream (or process::Queue) to the slave which corrections it needs to carry out, in order to mitigate interference with production tasks.
> The correction is communicated through a message:
> [code]
> message QoSCorrection {
> enum CorrectionType {
> KillExecutor = 1
> // KillTask = 2
> // Resize, throttle task
> }
> optional string reason = X;
> optional ExecutorID executor_id = X;
> // optional TaskID task_id = X;
> }
> [/code]
> And the slave will setup a handler to process these events. Initially, only executor termination is supported and cause the slave to issue 'containerizer->destroy()'.
