Github user rxin commented on the issue: https://github.com/apache/spark/pull/15899 Thanks for the example. I didn't even know that was possible in earlier versions. I just looked it up: looks like Scala 2.11 rewrites for comprehensions into map, filter, and flatMap. That said, I don't think it's a bad deal that this no longer works, given it was never intended to work and there's been a deprecation warning. I still maintain that it is risky to support this, because Scala users learn for comprehension not just for a simple "for filter yield", but as a way to chain multiple generators together, which is not really well supported by Spark (even if it is, it's a really bad operation for users to shoot themselves in the foot because it would be a cartesian product). Rather than faking it as a local collection, users should know RDD is not.
