[ http://issues.apache.org/jira/browse/HADOOP-432?page=comments#action_12436977 ]
Doug Cutting commented on HADOOP-432:
-------------------------------------
Perhaps the maximum size should be relative to the filesystem capacity, rather than absolute?
Otherwise a reasonable default setting will be difficult.
What is the public API? I think this should be a new FileSystem or DistributedFileSystem
method, not a change to delete(). Perhaps it could be called moveToTrash(). Then we also
need the ability to list the trash contents and undelete things.
> support undelete, snapshots, or other mechanism to recover lost files

> currently, once you delete a file it's gone forever.
> most file systems allow some form of recovery of deleted files.
> a simple solution would be an 'undelete' command.
> a more comprehensive solution would include snapshots, manual and automatic, with scheduling
options.
