> slave::statusUpdate() should always ACK the status update sent by executor

> Key: MESOS-5262

> Project: Mesos
> Issue Type: Improvement
> Components: slave
> Reporter: Qian Zhang
> Labels: mesosphere
>
> In {{slave::statusUpdate()}}, there are several scenarios where agent ignores
> a status update sent by the executor and will not send an ACK to the
> executor, e.g.:
> When agent receives a {{ShutdownFrameworkMessage}} from master,
> {{slave::shutdownFramework()}} will be called. In this method, we will set
> the state of framework to {{TERMINATING}} and send a
> {{ShutdownExecutorMessage}} to executor. When executor receives that message,
> usually it will kill the tasks and send {{TASK_KILLED}} status update to
> agent. Agent will receive that message and handle it in
> {{slave::statusUpdate()}}, but according to the currently logic of
> {{slave::statusUpdate()}}, it will ignore the status update if the state of
> framework is {{TERMINATING}}, so agent will not send an ACK to the executor.
> Since executor may rely on the ACK (e.g., HTTP command executor relies on the
> ACK of a terminal status update to terminate itself), we should enhance it
> such that executor can always get an ACK for the status update sent by it.
