Hairong Kuang updated HADOOP-1386:
----------------------------------
Attachment: path.patch
This patch disallows the construction of a Path from an empty string. Instead,
one has to explicitly specify "." to represent the current directory.
> The constructor of Path should not take an empty string as a parameter

> DFSShell should pass a user's home directory instead of an empty string for
> any operations on a user's home directory.

> data on our dfs cluster. Therefore, I marke it as a blocker to release 0.13
