Affects Version/s: 2.2.0
Fix Version/s: (was: 2.4.0)
Assignee: (was: Colin Patrick McCabe)
Summary: RawLocalFs#getFileLinkStatus does not fill in the link
owner and mode (was: CLONE - RawLocalFs#getFileLinkStatus does not fill in the
link owner and mode)
Cloned from HADOOP-9652, as that JIRA lays the groundwork but does not
completely fix the originally reported issue.
RawLocalFs#getFileLinkStatus does not fill in the link owner and mode
-
Key: HADOOP-10276
URL: https://issues.apache.org/jira/browse/HADOOP-10276
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Colin Patrick McCabe
{{RawLocalFs#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 the owner of the target they point to,
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.
