Subject [jira] [Created] (HDFS-12478) [WRITE] Command line tools for managing Provided Storage Backup mounts

---------------------------------

             Summary: [WRITE] Command line tools for managing Provided Storage Backup mounts
                 Key: HDFS-12478
                 URL: https://issues.apache.org/jira/browse/HDFS-12478
             Project: Hadoop HDFS
          Issue Type: Task
            Reporter: Ewan Higgs
            Priority: Minor


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}
