> When TaskImpl transitions to SUCCEEDED then it kills the other running task attempts. In the SUCCEEDED state the TaskImpl state machine ignores T_ATTEMPT_KILLED events from those killed attempts. Hence those completions events are not reported to the job. Every other attempt completion event is reported to the job.
