Matt Foley commented on HDFS-233:
---------------------------------

Dhruba and Sameer, the paper is pretty interesting.  Any interest in creating a sandbox branch for this feature, and contributing the implementation for review?

> 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.
