Chu Tong commented on HDFS-353:
-------------------------------
I tried this on hadoop trunk code and it seems already been fixed. Which
version of hadoop is this affecting?

> I propose turning this into a FileNotFoundException, which is more specific
> about the underlying problem. Including the full dfs URL would be useful too.
