  1. /Workspace is a directory (you can check by using the %sh magic command in a notebook)
  2. Well, the way I use my jars is by installing them on a cluster as a library. By then everything is mounted and the jars can be found. My jars reside in the /Filestore/jars directory and do not move or are not being copied.
