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}
