Thanks @srowen
[SPARK-25176](https://issues.apache.org/jira/browse/SPARK-25176) has a detail
description:
> I'm using the latest spark version spark-core_2.11:2.3.1 which
transitively depends on com.esotericsoftware:kryo-shaded:3.0.3 via the
com.twitter:chill_2.11:0.8.0 dependency. This exact version of kryo
serializer contains an issue [1,2] which results in throwing
ClassCastExceptions when serialising parameterised type hierarchy.
This issue has been fixed in kryo version 4.0.0 [3]. It would be great to
have this update in Spark as well. Could you please upgrade the version of
com.twitter:chill_2.11 dependency from 0.8.0 up to 0.9.2?
You can find a simple test to reproduce the issue [4].
