[jira] [Updated] (HADOOP-13092) RawLocalFileSystem is not case sensitive

["Andras Bokor (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-13092?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andras Bokor updated HADOOP-13092:
----------------------------------
    Description: 
RawLocalFileSystem is not case sensitive but I am not sure if it should be.
This class relays on the underlying OS filesystem

  was:
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].
