Dongjoon Hyun commented on SPARK-25075:
---------------------------------------
> It looks like scala 2.12 will still be the default, correct?
Yes, [~tgraves]. Our MiMa check is only verifying 2.12. After we have the
official 2.13 bits, we are able to switch the default Scala version.
> Are we planning on releasing the Spark tgz artifacts for 2.13 and 2.12 or
> only 2.12?
Both. SPARK-34218 added Scala 2.13 tgz artifacts and Maven publishing. Already,
we have both Scala 2.12/2.13 Snapshot Maven artifacts.
cc [~Gengliang.Wang] since he is the Apache Spark 3.2.0 release manager. The
above is the plan and if something goes out of order, we should fix it.
