Chuan Liu commented on HADOOP-8763:
-----------------------------------
>What is the problem this patch is trying to solve? An example would be good.
The following function in RawLocalFileSystem class will fail on Windows when
username is null, i.e. only set group ownership.
{noformat}
public void setOwner(Path p, String username, String groupname)
{noformat}
> Set group owner on Windows failed
