>                 Key: SPARK-4898
>                 URL: https://issues.apache.org/jira/browse/SPARK-4898
>             Project: Spark
>          Issue Type: Improvement

> We should consider replacing our modified version of {{cloudpickle}} with [Dill|https://github.com/uqfoundation/dill], since it supports both Python 2 and 3 and might do a better job of handling certain corner-cases.
> I attempted to do this a few months ago but ran into cases where Dill had issues pickling objects defined in doctests, which broke our test suite: https://github.com/uqfoundation/dill/issues/50.  This issue may have been resolved now; I haven't checked.
