I don't think this bug is so serious to fail an RC, it's only about metrics IIUC, and it's not a regression in 2.4.
I agree we should backport this fix to 2.3 and 2.4, and we should update our scala 2.12 jenkins build to use scala 2.12.7. cc Shane do you know how to change it? BTW end users can still use scala 2.12.7 with the Spark package built with scala 2.12.6, right?
