--------------------------------------------

             Summary: FileContext#getFileLinkStatus does not fill in the link 
owner and mode
                 Key: HADOOP-9652
                 URL: https://issues.apache.org/jira/browse/HADOOP-9652
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Colin Patrick McCabe


{{FileContext#getFileLinkStatus}} does not actually get the owner and mode of 
the symlink, but instead uses the owner and mode of the symlink target.  If the 
target can't be found, it fills in bogus values (the empty string and 
FsPermission.getDefault) for these.

Symlinks have an owner distinct from who created them, and getFileLinkStatus 
ought to expose this.

In some operating systems, symlinks can have a permission other than 0777.  We 
ought to expose this in RawLocalFilesystem and other places, although we don't 
necessarily have to support this behavior in HDFS.
