Review request for mesos, Joseph Wu, Qian Zhang, and Vinod Kone. Bugs: MESOS-8530 https://issues.apache.org/jira/browse/MESOS-8530 Repository: mesos Description ------- The default executor transitions a task to `TASK_KILLING` and marks its child container as being killed before posting a `KILL` call to the agent. The executor ignores kill requests for containers that are marked as being killed, and it doesn't remove this mark if the `KILL` call fails. This means that it's possible for tasks to get stuck in a `TASK_KILLING` state. This patch makes the default executor remove the killing mark if a `KILL` call fails. That way a scheduler can retry a kill.
