Re: Scala 2.11 support removed for Spark 3.0.0

Cool, Scala 2.12 compiles faster than Scala 2.11 . But it runs slower than Scala 2.11 by default. We may enable some compiler optimization options. On Mon, 25 Mar 2019 23:53:18 +0800 Sean Owen wrote I merged https://github.com/apache/spark/pull/23098 .

Scala 2.11 support removed for Spark 3.0.0
