Creates a snapshot of a snapshottable directory.
This operation requires owner privilege of the snapshottable directory. For more information on snapshots, see the Snapshots in HDFS article.

The usage is as follows:

$ hdfs dfs -createSnapshot <path> [<snapshotName>]

Arguments
<path>	The path of the snapshottable directory
[<snapshotName>]	The snapshot name, which is an optional argument. When it is omitted, a default name is generated using a timestamp with the format `'s’yyyyMMdd-HHmmss.SSS`, e.g. `s20130412-151029.033`
