> If a DoFn on the reducer throws a CrunchRuntimeException, the record you were processing when the exception was thrown. Since the record is usually some instance of Pair<K, Iterable<V>> and the Iterable is single-use, attempting to write the record to the log causes an exception to be thrown when we try to render the data in the Iterable by calling its iterator() method for the second time.
