Neil Conway commented on MESOS-6457:
------------------------------------
{{TASK_KILLING}} to {{TASK_LOST}} is definitely possible.
{{TASK_KILLING}} => {{TASK_LOST}} => {{TASK_RUNNING}} should be possible if
{{TASK_KILLING}} => {{TASK_RUNNING}} is possible (I haven't looked into whether
allowing the latter transition is a good idea or not...)
> Tasks shouldn't transition from TASK_KILLING to TASK_RUNNING.

> A task can currently transition from {{TASK_KILLING}} to {{TASK_RUNNING}}, if
> for example it starts/stops passing a health check once it got into the
> {{TASK_KILLING}} state.
> I think that this behaviour is counterintuitive. It also makes the life of
> framework/tools developers harder, since they have to keep track of the
> complete task status history in order to know if a task is being killed.
