> Currently Speculative tasks that didn't commit can show up as success of failures (depending on timing of commit). This is a bit confusing because that task didn't really succeed in the sense it didn't write anything.  
> I think these tasks should be marked as KILLED or something that is more obvious to the user exactly what happened.  it is happened to hit the timing where it got a commit denied exception then it shows up as failed and counts against your task failures.  It shouldn't count against task failures since that failure really doesn't matter.
> MapReduce handles these situation so perhaps we can look there for a model.
