Eli Collins updated HDFS-2802:
------------------------------

    Target Version/s: 3.0.0

Setting the target version to 3.0 since this will require a file system upgrade due to metadata
changes (eg HDFS-4126, HDFS-4086, and HDFS-4082) and we're heading to GA soon.

> Snapshots are point in time images of parts of the filesystem or the entire filesystem.
Snapshots can be a read-only or a read-write point in time copy of the filesystem. There are
several use cases for snapshots in HDFS. I will post a detailed write-up soon with with more
information.
