Subject [jira] [Created] (HADOOP-9652) FileContext#getFileLinkStatus does not fill in the link owner and mode
Date Tue, 18 Jun 2013 23:03:20 GMT
Colin Patrick McCabe created HADOOP-9652:
--------------------------------------------

             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.
