Review Comment:
   looks good to me, however I would suggest an additional minor refactor:
   deleteInputIterable, deleteOutputIterable are defined outside of new 
CloseableIterable<HiveBatchContext>. in the filterBatch method, can you move 
them as final fields into the CloseableIterable (both: deleteInputIterable, 
deleteOutputIterable, deleteOutputIterator), emphasizing that it owns all that 
stuff, so it's assumed to close them also
   otherwise, their closure makes sense
