Hairong Kuang commented on HADOOP-2514:
---------------------------------------
> I wasn't sure if preserving the parent path was a requirement of the current
> trash-bin design.
For each file in the trash bin, we could associate it with a meta file
recording its parent path. This is specially useful when files with the same
name under different directories get trashed.
> Trash and permissions don't mix

> Project: Hadoop
> Issue Type: New Feature
> Components: dfs
> Affects Versions: 0.16.0
> Reporter: Robert Chansler
> Fix For: 0.16.0

>
> Shell command "rm" is really "mv" to trash with the expectation that the
> server will at some point really delete the contents of trash. With the
> advent of permissions, a user can "mv" folders that the user cannot "rm". The
> present trash feature as implemented would allow the user to suborn the
> server into deleting a folder in violation of the permissions model.
> A related issue is that if anybody can mv a folder to the trash anybody else
> can mv that same folder from the trash. This may be contrary to the
> expectations of the user.
> What is a better model for trash?
