We made Scala 2.11 as default Scala version in Spark 2.0. Now, the next Spark version will be 3.0, so it's a great time to discuss should we make Scala 2.12 as default Scala version in Spark 3.0.
Scala 2.11 is EOL, and it came out 4.5 ago; as a result, it's unlikely to support JDK 11 in Scala 2.11 unless we're willing to sponsor the needed work per discussion in Scala community, https://github.com/scala/scala-dev/issues/559#issuecomment-436160166 We have initial support of Scala 2.12 in Spark 2.4. If we decide to make Scala 2.12 as default for Spark 3.0 now, we will have ample time to work on bugs and issues that we may run into. What do you think?
