isn't this going to add both scala jar 2.11 and 2.12 into class path at the same time?
Uh oh!

Thank you for review, @felixcheung . We assume that the Spark developers don't build both profiles without cleanup. This is a standard Spark way used since Spark 2.0.0.

BTW, as we see here, although we officially deprecated Scala-2.11 at Spark 2.4.1, it seems that we don't test Scala-2.12 actually during Spark 2.4.2 vote process. The community is still on Scala-2.11. It's time to switch
branch-2.4to Scala-2.12 if possible.There was a problem hiding this comment.

+1 on this. For next 2.4.3, we should have branch-2.4 default to Scala 2.12 as we will remove Scala 2.11 support in Spark 3.0
