Doug Cutting commented on HADOOP-4044:
--------------------------------------
> So is replacing 'return false;' with 'return new FSLinkBoolean(false)'.
That's not a fair comparison. I was talking about shorter names versus longer
names. You are talking about throwing exceptions versus adding a bit of code
to return a value. Both involve more-or-less code, but in one case that's the
only issue, in the other there's a lot more to it.

> 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.
