 I've been experimenting with the ISpark extension to IScala (
Objects created in the REPL are not being loaded correctly on worker nodes, leading to a ClassNotFound
exception. This does work correctly in spark-shell.
I was curious if anyone has used ISpark and has encountered this issue. Thanks!

Simple example:
In [1]: case class Circle(rad:Float)
In [2]: val rdd = sc.parallelize(1 to 10000).map(i=>Circle(i.toFloat)).take(10)14/11/11
13:03:35 ERROR TaskResultGetter: Exception while getting task resultcom.esotericsoftware.kryo.KryoException:
Unable to find class: [L$line5.$read$$iwC$$iwC$Circle;
