Hi, Just found this paragraph in http://spark.apache.org/docs/2.4.6/index.html#downloading:
"Spark runs on Java 8, Python 2.7+/3.4+ and R 3.1+. For the Scala API, Spark 2.4.6 uses Scala 2.12. You will need to use a compatible Scala version (2.12.x)." That seems to contradict the version of Scala in the pom.xml [1] which is 2.11.12. I think this says that Spark 2.4.6 uses Scala 2.12 by default which is incorrect to me. Am I missing something? My question is what's the official Scala version of Spark 2.4.6 (and others in 2.4.x release line)? (I do know that Spark 2.4.x could be compiled with Scala 2.12, but that requires scala-2.12 profile [2] to be enabled) [1] https://github.com/apache/spark/blob/v2.4.6/pom.xml#L158 [2] https://github.com/apache/spark/blob/v2.4.6/pom.xml#L2830 Pozdrawiam, Jacek Laskowski ---- https://about.me/JacekLaskowski "The Internals Of" Online Books <https://books.japila.pl/> Follow me on https://twitter.com/jaceklaskowski <https://twitter.com/jaceklaskowski>
