Chun-Hung Hsiao commented on MESOS-8927:
----------------------------------------
I'd like to add some notes here. This problem is actually nontrivial, because
AFAIK we don't have a reliable way to kill a container at any state.
> Default executor cannot kill tasks if `LAUNCH_NESTED_CONTAINER` is stuck.
