> In testing the DFS Trash feature, I've run across a couple of bugs.
> 1) Attempting to remove the same file fails when attempted within the same fs.trash.interval:
>     % bin/hadoop dfs -put file /file
>     % bin/hadoop dfs -rm /file
>     Moved to trash: /file
>     % bin/hadoop dfs -put file /file
>     % bin/hadoop dfs -rm /file
>     rm: Failed to move to trash: /file
> 2) Removing a file within a directory, followed by removing the directory creates a bizzare
hierarchy within /Trash:
>     % bin/hadoop dfs -mkdir /dir
>     % bin/hadoop dfs -put file /dir/file
>     % bin/hadoop dfs -rm /dir/file
>     Moved to trash: /dir/file
>     % bin/hadoop dfs -rmr /dir
>     Moved to trash: /dir
>     % bin/hadoop dfs -lsr /Trash
>     /Trash/Current  <dir>
>     /Trash/Current/dir      <dir>
>     /Trash/Current/dir/dir  <dir>     <-- This is weird; potentially related
to a rename case not fixed by HADOOP-1623 ???
>     /Trash/Current/dir/file <r 3>   10
