Raghu Angadi commented on HADOOP-4044:
--------------------------------------
> catch (SymLinkNotFollowedException e) { [...]
Just to clarify. the above was only mentioned as a way for _DFSClient_ to
inform _FileSystem_ to overcome limitation of return type for open(). Not as
an exception thrown by NameNode to client.
Of course, exception is not necessary if open and friends are modified to
return class/struct etc.

> 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.
