Colin Patrick McCabe commented on HADOOP-9652:
----------------------------------------------
OK. I have reverted the patch.
Here is a summary of the issues we know of with the original patch:
* Fallback path should handle MacOS (HADOOP-9783)
* Issue with URI fragment handling and DistCp (MAPREDUCE-5430)
* Stray {{System.println}} caused some TestDFSShell failures
* must not use "{{bash -c}}"
So we need a new version of the patch which addresses all of these.
Additionally, can you touch a file in each project (i.e., hadoop-hdfs-project,
hadoop-mapreduce-project, hadoop-yarn-project), so that we get the full Jenkins
run, rather than just a Jenkins run on common?

> {{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.
