Andras Bokor commented on HDFS-10385:
-------------------------------------
Previously, I had a discussion with [~cnauroth] and [~ste...@apache.org] about
changing rename behaviors and finally that JIRA was resolved with "Later"
resolution. Please check the HADOOP-13082 for details. Even if we change
behaviors it should be part of a bigger and more complex change because there
are lot of differences between rename behaviors in different FS
implementations.
Based on that this should be closed either. What do you guys think?
> 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
> Assignee: Xiaobing Zhou
>
> 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.
