---------------------------------

             Summary: SingleUseIterable exceptions mask CrunchRuntimeExceptions thrown in the reducer
                 Key: CRUNCH-248
                 URL: https://issues.apache.org/jira/browse/CRUNCH-248
             Project: Crunch
          Issue Type: Bug
          Components: Core
            Reporter: Josh Wills
            Assignee: Josh Wills
             Fix For: 0.8.0
         Attachments: CRUNCH-248.patch

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.
