I am afraid that {{TASK_LOST}} is not a terminal state. A slave rejoining the
cluster after a master failover might make tasks go from {{TASK_LOST}} to
{{TASK_RUNNING}}.
If I understand Neil correctly, tasks could do the {{TASK_KILLING => TASK_LOST
=> TASK_RUNNING}} transition only if an executor transitions them while the
slave is disconnected from the cluster.

I though {{TASK_LOST}} is a terminal state, hence the transition is valid.

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...)

[~zhitao] yes, this behaviour only affect the default and the command executors.
I believe that it is still possible for a task in {{TASK_KILLING}} to
transition to {{TASK_LOST}}. Given that {{TASK_LOST}} is not a terminal state,
I don't know if it would then be possible for the task to transition to
{{TASK_RUNNING}} instead of to {{TASK_KILLING}}/{{TASK_KILLED}}. Maybe [~neilc]
knows.

Is this behavior only possible when framework opt-in to use Mesos's own health
check (aka custom executors which do not use Mesos health check should not
affected)?
