             Summary: RawLocalFileSystem is not case sensitive
                 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].
