Prasad Chakka commented on HADOOP-4970:
---------------------------------------
since 0.20 is not already released, it would be nice if you can put this in
0.20.
> Use the full path when move files to .Trash/Current

>
> When a directory or file is deleted using rm or rmr, the subtree is moved
> directly to .Trash/Current. If there are two deleted objects with the same
> name but with different original paths it is not feasible to undelete them
> without storing additional information regarding the original paths. Instead
> if the full path of the deleting object is used while moving (replicating the
> complete path in .Trash/Current) it will be easier to undelete objects to its
> original paths.
