For HMS, I think we basically want to have separate DBs for different base filesystems. HMS has the path of the table (e.g. functional.alltypes == hdfs://blah blah blah). When we go from hdfs to ozone, that changes. Not sure about erasuring coding, but the safest thing would be to keep them separate.

See the METASTORE_DB below (and potentially the RANGER_POLICY_DB as well).

We used to have a problem where different Impala checkouts on the same machine would clobber each other's HMS database, so we incorporated the directory name into it.
