Sanjay Radia commented on HDFS-2802:
------------------------------------

Aaron
  wrt to your alternate proposal, folks can get confused about which of the two series of

and also reflect that in the title inside the document.

> 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.
