Sean Owen commented on SPARK-17367:
-----------------------------------
Ah, I see, so it's definitely needed. Hm. I think it's fine to have this issue
as a pointer. Is there any possible workaround one could imagine for this that
could be implemented in Spark? if not I am not sure what the action would be
here. It kind of sounds like SPARK-17368 could be a different manifestation of
the same problem anyway; it may not even be shell-specific?
> Cannot define value classes in REPL
> -----------------------------------
>
> Key: SPARK-17367
> URL: https://issues.apache.org/jira/browse/SPARK-17367
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell
> Reporter: Jakob Odersky
>
> It is currently not possible to define a class extending `AnyVal` in the
> REPL. The underlying reason is the {{-Yrepl-class-based}} option used by
> Spark Shell.
> The report here is more of an FYI for anyone stumbling upon the problem, see
> the upstream issue [https://issues.scala-lang.org/browse/SI-9910] for any
> progress.
