Review Comment:
Currently, to obtain Fileset metadata, we need to `loadCatalog` first, and
then call `asFilesetCatalog().getFileLocation()`. If the Catalog is not cached
here, two RPCs are required for each file operation. Considering that changes
to the Catalog are not very frequent, these requests may be unnecessary.
