I call attention to https://github.com/apache/spark/pull/28971 which represents part 1 of several changes that are the last large change for Scala 2.13, except for REPL updates: dealing with the fact that default collection types will be immutable.
The goal of course is to cross-compile without separate source trees, if possible, and I think this is the best bet, which we've discussed for over a year. Before merging or applying this strategy more widely, I wanted to call attention to it. --------------------------------------------------------------------- To unsubscribe e-mail: dev-unsubscr...@spark.apache.org
