For basic exercises, advanced modules such as `solr`, `spark`, `graph, `graph-server` are not used. Would it be OK to delete the `resources/xxx` directory corresponding to those module to save some storage space?
I did so but `dse cassandra` didn't start, because of some environment variables are not defined.
Maybe this is not a wise thing to do. Just wondered if there is a safeway to install a minimum lightweigt DSE for simple exercises (where nodes are created / deleted often).
