HeartSaVioR edited a comment on issue #21339: [SPARK-24287][Core] Spark -packages option should support classifier, no-transitive, and custom conf URL: https://github.com/apache/spark/pull/21339#issuecomment-476404245 I'm not sure about `transitive` and `conf` (might be good to have) but I've been using `exclude` quite often in other project (DISCLAIMER: Actually I introduced similar functionality there) since transitive dependencies often bring conflicts. IMHO, once we support `--packages` option which is a mechanism on dynamic dependency control (instead of uber jar), 'exclude' seems good for completeness of feature. We can still control it via packaging with uber jar, but there're some situations we tend to rely on `--packages` (spark-shell is one of example, but `notebook` or `submitter` tools of Spark may also want to deal with `--packages` too.)
