[jira] [Updated] (SPARK-21420) Support array type code 'q' and 'Q'

     [ https://issues.apache.org/jira/browse/SPARK-21420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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 might be fixed by adding back deleted lines in https://github.com/apache/spark/pull/18444/commits/cafa5fdc22270847657a29b0470dfd0ca4ad4ad2
