Note: A set of subdirectories will be created under the specified data directory. Those subdirectories will be named by the UUID of the corresponding metadata or data service. In addition, the subdirectory corresponding to the metadata service will have a file named ".mds" to differentiate it from the data service directories. The presence of that ".mds" file is used to re-start the service as a metadata service rather than a data service.
Since a set of subdirectories will be created for the embedded federation, it is important to give each embedded federation its own data directory. Otherwise a new federation starting up with another federation's data directory will attempt to re-start that federation.
