fangshil commented 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-476466098 We have been supporting --packages internally for more than 2 years, and restricted our use cases for ad-hoc testing in shell and notebook. As a typical use case, use starts spark-shell as part of the development process for easy debugging for pieces of the job logic, before assembling a whole prod job through a build tool. Supporting a powerful --package similar using to a build tool were a requirement especially for us(a java company). In our experience, the four options we added have covered all the corner case so far. My thoughts are mostly aligned with @HeartSaVioR, while in addition, I think both the 4 options we proposed are 'good for completeness of this feature'.
