DFS Trash feature bugs
----------------------
Key: HADOOP-1665
URL: https://issues.apache.org/jira/browse/HADOOP-1665
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.13.1
Reporter: Nigel Daley
Priority: Blocker
Fix For: 0.14.0
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
