Thanks for the info Holden.
So it seems both the jira and the comment on the developer list are over a
year old. More surprising, the jira has no assignee. Any particular reason
for the lack of activity in this area?
Is writing scala/java the only work around for this? I hear a lot of people
say python is the gateway language to scala. It is because of issues like
this that people use scala for Spark rather than python or eventually
abandon python for scala. It just takes too long for features to get ported
over from scala/java.
