Stavros Kontopoulos commented on SPARK-23153:
---------------------------------------------

[~cloud_fan] is there going to be another 2.4.x release? Does it make sense to backport?

> Currently local dependencies are not supported with Spark on K8S i.e. if the user has code or dependencies only on the client where they run {{spark-submit}} then the current implementation has no way to make those visible to the Spark application running inside the K8S pods that get launched.  This limits users to only running applications where the code and dependencies are either baked into the Docker images used or where those are available via some external and globally accessible file system e.g. HDFS which are not viable options for many users and environments
