> It looks like it's possible for Spark to recompute some RDDs that get reloaded between output runs. When this happens, the Broadcast<byte[]> field that contains the serialized Configuration object is null b/c we haven't declared an output RDD to run against yet. I added a change to ensure that the serialized Configuration object is always defined, even before we generate any output, to ensure that we don't throw an NPE.
