Raghu Angadi commented on HADOOP-4044:
--------------------------------------
> If the extra RPC is a problem, then a FileSystem can implement open()
> directly itself as an optimization.
That imposes restriction on what SymLink can point to.
> Exceptions should not be used for normal program control.
agreed. we could of course propose another FS.open() that returns something
more than an FSInputStream.
> 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.
