> {{LocalMetadataStore#put(DirListingMetadata)}} only puts the metadata into {{dirHash}},
thus all {{FileStatus}} s are missing from {{LocalMedataStore#fileHash()}}, which makes it
confuse to use.
> So in the current way, to correctly put file status into the store (and also set {{authoriative}}
flag), you need to run  {code}
> List<PathMetadata> metas = new ArrayList<PathMetadata>();
> boolean authorizative = true;
> for (S3AFileStatus status : files) {
>    PathMetadata meta = new PathMetadata(status);
>    store.put(meta);
> }
> DirListingMetadata dirMeta = new DirMeta(parent, metas, authorizative);
> store.put(dirMeta);
> {code}
> Since solely calling {{store.put(dirMeta)}} is not correct, and calling {{store.put(dirMeta);}}
after putting all sub-file {{FileStatuss}} does the repetitive jobs. Can we just use a {{put(PathMetadata)}}
and a {{get/setAuthorative()}}   in the MetadataStore interface instead?
