Description

If a running attempt is lost on a tracker, a attempt-level cleanup with the same attempt-id is launched for it. In such cases the events are not logged correctly and instead of logging

Task Reduce Start
Attempt Reduce Start
Attempt Reduce Killed 
Task reduce Killed

it logs

Task Reduce Start
Task Reduce Failed
Attempt Reduce Start
Attempt Reduce Killed
