> 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.
