Steve Loughran commented on HADOOP-9805:
----------------------------------------
Now that Hadoop is 2.7+ only the new nativeio operations can be used for rename & other things, which fail better
> Refactor RawLocalFileSystem#rename for improved testability.

> {{RawLocalFileSystem#rename}} contains fallback logic to provide POSIX rename behavior on platforms where {{java.io.File#renameTo}} fails. The method returns early if {{java.io.File#renameTo}} succeeds, so test runs may not cover the fallback logic depending on the platform.
