Hi Josh,
Yes, that seems to be the issue. As I commented out in the JIRA, just
yesterday (after I had sent the email), such simple queries like the
following killed spark-shell:
Seq(1).toDF.groupBy('value).count.show
Hoping to see it get resolved soon. If there's anything I could help
you with to fix/reproduce the issue, let me know. I wish I knew how to
write a unit test for this. Where in the code to look for inspiration?
Pozdrawiam,
Jacek Laskowski
