   Two possible solutions to the problem of failed compactions leaving files around.
   
    * Could place an entry in the metadata table like `row=<tablet row> family=compacting qualifier=<uri>` for files currently being created by compactions.  When a tablet is loaded it looks for these and deletes the URIs and then the metadata entries.  When a file is added to the metadata table for a compaction, it can delete the `compacting` family and add the `file` family atomically in the same mutation.
    * Could create a tool that looks for files in DFS that are not in metadata table.  Admins could periodically run this tool.
