Here are two interesting issues (with PRs) concerning Java APIs for Spark 2.x. Details and discussion inside, and comments requested.
https://issues.apache.org/jira/browse/SPARK-3369 This concerns fixing Iterator/Iterable problems in some Java API methods, to make them consistent with Scala. This allows real streaming operation in, say, flatMap, but it's an API change that's definitely going to make people change their code. https://issues.apache.org/jira/browse/SPARK-4819 This concerns the fate of Guava Optional in the Java API, and what to replace it with. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@spark.apache.org For additional commands, e-mail: dev-h...@spark.apache.org
