Subject [jira] Created: (HADOOP-1665) DFS Trash feature bugs
Date Mon, 30 Jul 2007 22:53:52 GMT
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
