I agree that they're not administrative operations in the sense that they
don't strictly require super user privilege, but they are "administrative"
in the sense that they will most-often be used by those administering HDFS.
The HdfsAdmin class should not be construed to contain only operations
which require super user privilege, even though that happens to be the case
right now. It's intended as just a public API for HDFS-specific operations.

Regardless, my point is not necessarily that these operations should go
into the HdfsAdmin class, but rather that they shouldn't go into the
FileSystem class, since the snapshots API doesn't seem to me like it will
generalize to other FileSystem implementations.
