> Key: SPARK-668
> URL: https://issues.apache.org/jira/browse/SPARK-668
> Project: Spark
> Issue Type: Bug
> Components: Java API
> Affects Versions: 0.6.1, 0.7.0
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Fix For: 0.7.0, 0.6.2

> As described in https://groups.google.com/d/topic/spark-users/KrVIf-DHg60/discussion, calls to JavaRDdLike.flatMap(PairFlatMapFunction) may be falsely rejected by the compiler with "cannot find symbol; method: flatMap" errors.
> Here's a complete standalone example that reproduces the problem:
> https://gist.github.com/4640356
> I tried implementing a similar example in pure-Java (no Spark code) and was able to get the proper typechecking, so I suspect that this might be a Scala compiler bug.
