Subject [jira] Created: (HADOOP-730) Local file system uses copy to implement rename
Date Thu, 16 Nov 2006 08:08:37 GMT
Local file system uses copy to implement rename
-----------------------------------------------

                 Key: HADOOP-730
                 URL: http://issues.apache.org/jira/browse/HADOOP-730
             Project: Hadoop
          Issue Type: Bug
          Components: fs
    Affects Versions: 0.8.0
            Reporter: Owen O'Malley
         Assigned To: Owen O'Malley
             Fix For: 0.9.0


There is a variable LocalFileSystem.useCopyForRename that is set to true. When true, the local
file system will implement rename as a copy followed by a delete. This is likely a performance
problem. Is there a reason that useCopyForRename is set?
