> I know that adding support of a new scala version is something that can be time consuming and would require some testing phase, but it would be great at least to have this support in integration-test module (no scala suffix supported there, yet).
> We can use livy with spark 2.4.0 with scala 2.12 and livy java client, but we cannot use integration-test module for testing because it fails on scala compatibility issues, such as 
> {code:java}
> java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;
