update(taskStatus)
Communicate the state of managed tasks. It is crucial that a terminal update (e.g., TASK_FINISHED, TASK_KILLED or TASK_FAILED) is sent to the agent as soon as the task terminates, in order to allow Mesos to release the resources allocated to the task. The scheduler must explicitly respond to this call through an ACKNOWLEDGE message (see ACKNOWLEDGED in the Events section below for the semantics). The executor must maintain a list of unacknowledged updates. If for some reason, the executor is disconnected from the agent, these updates must be sent as part of SUBSCRIBE request in the unacknowledged_updates field.

Parameters:
