My apologies for following my own post, but a friend just pointed out that if I
use kryo with reference counting AND copy-and-paste, this runs.
However, if I try to "load <file>", this fails as described below.
I thought load was supposed to be equivalent?

Subject: variant record by case classes in shell fails?
Greetings!
For me, the code below fails from the shell.However, I can do essentially the
same from compiled code, exporting the jar.
If I use default serialization or kryo with reference tracking, the error
message tells me it can't find the constructor for "A".If I use kryo with
reference tracking, I get a stack overflow.
I'm using Spark 1.2.1 on AWS EMR (hadoop 2.4).
I've also tried putting this code inside an object.
Is this just me? Am I overlooking something obvious?
Thanks!

sealed class AorBcase class A(i: Int) extends AorBcase class B(i: Int, j: Int)
extends AorB
sc.parallelize(0.until(1)).map{ _ => val x = A(1) x}.collect()
