Hi Bertrand, We should probably add a SparkContext.pickleFile and RDD.saveAsPickleFile that will allow saving pickled objects. Unfortunately this is not in yet, but there is an issue up to track it: https://issues.apache.org/jira/browse/SPARK-1161.
In 1.0, one feature we do have now is the ability to load binary data from Hive using Spark SQL’s Python API. Later we will also be able to save to Hive.
