> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.0.0, 2.5.0
> Reporter: Uma Maheswara Rao G

> Currently snapshot docs contains the cp command details for copying the
> snapshot files to regular dfs tree.
> http://hadoop.apache.org/docs/r2.3.0/hadoop-project-dist/hadoop-hdfs/HdfsSnapshots.html#Snapshot_Paths
> Copying a file from snapshot s0:
> hdfs dfs -cp /foo/.snapshot/s0/bar /tmp
> Since there are important properties(acls, xattrs..etc) for a file may need
> to copy back. But looking at this doc may mislead to copy with out using any
> options. So, It may be worth mentioning aboit that properties. Infact it
> should copy all properties by default from snapshot file.
