Xiang Gao updated SPARK-21420:
------------------------------
Description:
Python's array type {{q}} and {{Q}} are currently not supported by
{{net.razorvine.pickle}}, and therefore not supported by spark yet.
On some platform, {{q}} is a signed 64bit integer, which in theory should be
supported because it has the same size as {{Long}} in Scala.
See https://github.com/apache/spark/pull/18444#discussion_r126072461
This issue can be easily fixed by adding back deleted lines in
https://github.com/apache/spark/pull/18444/commits/cafa5fdc22270847657a29b0470dfd0ca4ad4ad2
