   > This will be an issue even without any determinism issue, for example when 
there is speculative execution - as a race condition.
   
   But do we want one more situation where it breaks?
   
   And my other concern is the Hadoop's file output committer I cannot see any 
guarantees what will happen if a Hadoop task is re-commited with different data 
(because of indeterminism we might have different data).
