James Kennedy updated HDFS-233:
-------------------------------


I'd like to see this task get more traction. A snapshot mechanism would be very valuable for
those of us relying on HDFS to hold critical information.

> Support HDFS snapshots. It should support creating snapshots without shutting down the
file system. Snapshot creation should be lightweight and a typical system should be able to
support a few thousands concurrent snapshots. There should be a way to surface (i.e. mount)
a few of these snapshots simultaneously.
