> Currently there's scheduledTime in TaskStartedEvent. That means we can only get the scheduled time for the first task attempt (start_time_first_taskattempt - scheduledTime). But we can't get it for the second task attempt if the first task attempt failed. The schedule should be task attempt level. 
> Getting the time spent on scheduling might be useful for performance analysis and tez-ui visualization.
