> When a failed task attempt container is stuck in FAIL_FINISHING_CONTAINER
> state for some time, we observe two task attempts are launched simultaneously
> even when speculative execution is disabled.
> This results in the below message shown in the killed attempts, indicating
> speculation has occurred. This is an issue for jobs which require speculative
> execution to be strictly disabled.
