> This is a task for implementing the command line interface for attaching a 
> PROVIDED storage backup system (see HDFS-9806, HDFS-12090).
> # The administrator should be able to mount a PROVIDED storage volume from 
> the command line. 
> {code}hdfs attach -create [-name <name>] <hdfs directory to backup> <backup 
> path (external)>{code}
> # Whitelist of users who are able to manage mounts (create, attach, detach).
> # Be able to interrogate the status of the attached storage (last time a 
> snapshot was taken, files being backed up).
> # The administrator should be able to remove an attached PROVIDED storage 
> volume from the command line. This simply means that the synchronization 
> process no longer runs. If the administrator has configured their setup to no 
> longer have local copies of the data, the blocks in the subtree are simply no 
> longer accessible as the external file store system is currently inaccessible.
> {code}hdfs attach -remove <name> [-force | -flush]{code}
