Todd Lipcon updated HDFS-2016:

    Attachment: hdfs-2016.txt

Here's a basic patch.

There are a couple issues still to work out with how this interacts with the 2NN, but the
basic structure should be good.

> This JIRA is for the infrastructure that periodically scans the storage directories for
files that are no longer necessary and "archives" them. The default archival is just to delete
them, but we may implement something fancier in the future (eg move to SAN or HDFS)
