Konstantin Shvachko commented on HDFS-245:
------------------------------------------
> The contract of a FileSystem implementation, from the outside, in the
> presence of links, is to map paths to either bytes or to an external link.
> *How it chooses to implement that internally is a separate issue.*
If this means NameNode and DistributedFileSystem may throw an exception in case
of paths with external links, which is handled on the FileSystem level, then
that resolves the issue for me.
> Create symbolic links in HDFS

> 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.
