## What changes were proposed in this pull request? This PR makes Spark's default Scala version as 2.12, and Scala 2.11 will be the alternative version. This implies that Scala 2.12 will be used by our CI builds including pull request builds. We'll update the Jenkins to include a new compile-only jobs for Scala 2.11 to ensure the code can be still compiled with Scala 2.11. ## How was this patch tested? existing tests Closes #22967 from dbtsai/scala2.12.
