Aaah, this is getting into the binary compatibility issue. Adding the
print(num) method to the interface JavaDStreamLike (Scala traits boil down to
Java interfaces) is going to break existing implementations of the abstract
class. But that is probably okay because I doubt any one has subclasses
JavaDStreamLike. You will have to add the mima binary check exception in this
file.
https://github.com/apache/spark/blob/master/project/MimaExcludes.scala
And you have to add exclusions for
`ProblemFilters.exclude[MissingMethodProblem]("org.apache.spark.streaming.api.java.JavaDStreamLike.print")`
for Spark 1.2
Let me know if you need more information.
