> In SPARK-6949 davies documented a couple of bugs with Py4J that prevented Spark from registering a converter for date and datetime objects. Patched in https://github.com/apache/spark/pull/5570.
> Specifically https://github.com/bartdag/py4j/issues/160 dealt with ListConverter automatically converting bytearrays into ArrayList instead of leaving it alone.
> Py4J #160 has since been fixed in Py4J, since the 0.9 release a couple of months after Spark #5570. According to spark-core's pom.xml, we're using 0.10.3.
> We should remove this patch on ListConverter since the upstream package no longer has this issue.
