> In a multi-cluster environment it is sometimes useful to operate on the root / slash directory of an HDFS cluster. E.g., list all top level directories. Quoting the comment in {{ViewFs}}:
> {code}
>  *   A special case of the merge mount is where mount table's root is merged
>  *   with the root (slash) of another file system:
>  *   <ul>
>  *   <li>    fs.viewfs.mounttable.default.linkMergeSlash=hdfs://nn99/
>  *   </ul>
>  *   In this cases the root of the mount table is merged with the root of
>  *            <b>hdfs://nn99/ </b> 
> {code}
