[SPARK-25956] Make Scala 2.12 as default Scala version in Spark 3.0 ## 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 You can merge this pull request into a Git repository by running: $ git pull https://github.com/dbtsai/spark scala2.12 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/22967.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #22967 ---- commit 635e6e23c5066018fd656738c51d02df8130585e Author: DB Tsai <d_tsai@...> Date: 2018-11-06T22:13:11Z make scala 2.12 as default commit 5011dc07c6462e7f5a9974a0b9b28f937d678297 Author: DB Tsai <d_tsai@...> Date: 2018-11-06T23:11:34Z sbt change commit b4b9cb95df35b754432fb74361c32f563d1661b0 Author: DB Tsai <d_tsai@...> Date: 2018-11-07T00:02:22Z address feedback commit 292adb111750cfe98593f12f64ebe11067482b44 Author: DB Tsai <d_tsai@...> Date: 2018-11-07T00:35:58Z address feedback ---- --- --------------------------------------------------------------------- To unsubscribe, e-mail: reviews-unsubscr...@spark.apache.org For additional commands, e-mail: reviews-h...@spark.apache.org
