Aaron T. Myers commented on HDFS-4076:
--------------------------------------
Can I please have a few days to review this code and the updated design doc?
Thanks.
Also, I assume that this will be checked into the HDFS-2802 branch? If so, I
think we should create an "HDFS-2802" fix version and set that as the
target/fix version for the sub-tasks of HDFS-2802. If you guys agree, I can
take care of that.

> The snapshot of a file shares the blocks with the original file in order to
> avoid copying data. However, the snapshot file has its own metadata so that
> it could have independent permission, replication, access time, etc.
