Viewing the Contents of a Snapshot
At the top level of each volume is a directory called
.snapshot
containing all the snapshots for the volume.
You can view the directory with hadoop fs
commands or
by mounting the cluster with NFS. To prevent recursion problems,
ls
and hadoop fs -ls
do not show the
.snapshot
directory when the top-level volume
directory contents are listed. You must navigate explicitly to the
.snapshot
directory to view and list the snapshots for
the volume.
Example:
root@node41:/opt/mapr/bin# hadoop fs -ls /myvol/.snapshot
