Although like you said, spark support for scala 2.12 is beta anyway then shouldn’t we get
it to a working state by basing on 2.12.7? There shouldn’t be a stability issue since it
is not officially “supported”

Subject: Re: On Scala 2.12.7

My major concern is how it will affect end-users if Spark 2.4 is built with Scala versions
prior to 2.12.7. Generally I'm hesitating to upgrade Scala version when we are very close
to a release, and Scala 2.12 build of Spark 2.4 is beta anyway.

I'm forking the discussion about Scala 2.12.7 from the 2.4.0 RC vote thread.

2.12.7 was released yesterday, and, is even labeled as fixing Spark
2.4 compatibility! We should
look into it, yes.

Darcy identified, and they fixed, this issue: while finishing the work for
Scala 2.12.

However we already worked around this in Spark, no? at

So we should go ahead and update to use 2.12.7, yes, and undo this workaround?
But this doesn't necessarily block a 2.4.0 release, if it's already
worked around.
