Sean Owen updated SPARK-12604:
------------------------------
Description:
Another minor API problem I noticed while digging around. The following Java
API methods return a Long as part of their signature, but it's a
{{scala.Long}}, not a {{java.lang.Long}}:
* countByKey
* countApproxDistinctByKey
Other similar methods correctly return a Java Long, like countByValue, and the
whole Java streaming API.
Of course, changing this is probably the right thing to do, but also is an API
change. I think it's worth fixing up

Summary: Java count(AprroxDistinct)ByKey methods return Scala Long not
Java (was: Java countByKey, zipWith*, etc methods return Scala Long not Java)
