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?
