dhruba borthakur updated HDFS-245:
----------------------------------
Attachment: symlink17-hdfs.txt
symlink17-common.txt
Here is a patch that conforms to the modified consensus arrived earlier in the
week. I would like everybody to review the symlink17-common.txt patch that has
changes to the FileSystem API.
This code is not yet tested in great detail and is uploaded only for review
purposes. (Also, this patch does not yet modify the FileContext API.)

> 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.
