   > Can you expand on this, what does "mount" mean here in a distributed environment. The place $SPARK_CONF_DIR is pointing has to be on distributed filesystem. if its pointing to local disk how do you mount that on remote pod.
   
   @tgravescs, Hi Thomas Graves, the mount here refers to the kubernetes feature that it lets us mount ConfigMaps as Volumes. More details here. https://kubernetes.io/docs/concepts/storage/volumes/#configmap. `SPARK_CONF_DIR` is not required to be on a distributed filesystem.
   
   I have also updated the description with more details how the Kubernetes config map will work here. 
   
   Thanks a lot for taking a look though, do you have more comments? can you please help review this patch !
