   We have considered building a custom registrator but decided not to do that for exactly the same reason you describe: users will have to set it and Kryo will not work out of the box. Instead, we got rid of Guava in places that were exposed to Spark.
   
   I think `RewriteDataFilesAction` is relatively new so we haven't caught it.
