Jakob Odersky commented on SPARK-17103:
---------------------------------------
That's true, the spark repl is basically just a thin wrapper around the scala
repl, with custom initialization and settings. One of the settings,
"-Yrepl-class-based", has caused issues previously and seems to be the culprit
here again (I can reproduce the issue by running a normal scala repl with
-Yrepl-class-based{/code} enabled).
There is one option that is set by spark and has caused previous issues
> Can not define class variable in repl
