-----------------------------------
Summary: Remove unnecessary Py4J ListConverter patch
Key: SPARK-17679
URL: https://issues.apache.org/jira/browse/SPARK-17679
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 2.0.0
Reporter: Jason White
Priority: Minor
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.
