Doug Cutting commented on HADOOP-4044:
--------------------------------------
> I see you are changing the subject.
I am saddened that you think that. I have tried to say the same thing in many
different ways, to make myself better understood. I will say it one last time:
I will veto any patch that uses exceptions to to communicate links within the
FileSystem implentation. Exceptions are an inappropriate mechanism for
communicating normal, expected values. In the namesystem sub-component of
HDFS, which stores links, and any other sub-components between that and the
generic FileSystem API, links are normal, expected events, even links to
different FileSystems. There. I've said it again. I am now done saying it.
Do not expect me to respond again about the issue of using exceptions to
communicate the presence of links in HDFS. My answer will not change. Let's
move on.

> HDFS should support symbolic links. A symbolic link is a special type of file
> that contains a reference to another file or directory in the form of an
> absolute or relative path and that affects pathname resolution. Programs
> which read or write to files named by a symbolic link will behave as if
> operating directly on the target file. However, archiving utilities can
> handle symbolic links specially and manipulate them directly.
