Chris A. Mattmann commented on SPARK-3200:
------------------------------------------

how did this get resolved other than simply saying in 1.6 it worked? I'm confused.

>                 URL: https://issues.apache.org/jira/browse/SPARK-3200
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Shell
>    Affects Versions: 1.1.0
>            Reporter: Prashant Sharma

> Reproducer:
> {noformat}
> val a = sc.textFile("README.md").count
> case class A(i: Int) { val j = a} 
> sc.parallelize(1 to 10).map(A(_)).collect()
> {noformat}
> This will happen only in distributed mode, when one refers something that refers sc and not otherwise. 
> There are many ways to work around this, like directly assign a constant value instead of referring the variable.
