> Key: HADOOP-13092
> URL: https://issues.apache.org/jira/browse/HADOOP-13092
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.23.0
> Reporter: Andras Bokor
> Assignee: Andras Bokor
>
> FileSystemContractBaseTest#testRenameFileMoveToNonExistentDirectory: creates a file then move it to a non-existing directory. It should fail but it will not (with RawLocalFileSystem) because in RawLocalFileSystem#rename(Path, Path) method we have a fallback behavior that accomplishes the rename by a full copy. The full copy will create the new directory and copy the file there.
> I see two possible solutions here:
> # Remove the fallback full copy behavior
> # Before full cp we should check whether the parent directory exists or not. If not return false an do not do the full copy.
> The fallback logic was added by [HADOOP-9805|https://issues.apache.org/jira/browse/HADOOP-9805].
