I know that the code itself would not be the same, but it would be useful to at least have the pom/build.sbt transitive dependencies different when fetching the artifact with a specific classifier, don't you think ? For now I've overriden them myself using the dependency versions defined in the pom.xml of spark. So it's not a blocker issue, it may be useful to document it, but a blog post would be sufficient I think. The problem here is that it's not directly something that maven repo is set up to deal with. What could be done would be to publish multiple pom-only artifacts, spark-scala-2.11-hadoop-2.6.pom which would declare the transitive stuff appropriately for the right version. You wouldn't need to actually rebuild everything, just declare a dependency on the spark 2.2 artifacts excluding all of hadoop 2.2, pulling in 2.6. This wouldn't even need to be an org.apache.spark artifact, just something any can build and publish under their own name. Volunteers?
