Aihua Xu created HDFS-10385:
-------------------------------
Summary: LocalFileSystem rename() function should return false
when destination file exists
Key: HDFS-10385
URL: https://issues.apache.org/jira/browse/HDFS-10385
Project: Hadoop HDFS
Issue Type: Bug
Components: fs
Affects Versions: 2.6.0
Reporter: Aihua Xu
Currently rename() of LocalFileSystem returns true and renames successfully
when the destination file exists. That seems to have different behavior from
DFSFileSystem.
If they can have the same behavior, then we can use one call to do rename
rather than checking if destination exists and then making rename() call.
