Sean Owen commented on SPARK-14005:
-----------------------------------
That's not the argument: it's the additional API overhead for very little gain.
You're proposing this only because Scala collections have them, but emulating
Scala collections isn't a goal for RDDs, even if they share method names for
similar operations.
