[SPARK-24137][K8S] Mount local directories as empty dir volumes.#372
Conversation
Drastically improves performance and won't cause Spark applications to fail because they write too much data to the Docker image's specific file system. The file system's directories that back emptydir volumes are generally larger and more performant. Has been in use via the prototype version of Kubernetes support, but lost in the transition to here. Author: mcheah <mcheah@palantir.com> Closes apache#21238 from mccheah/mount-local-dirs.
