------------------------------------------------------------

Actually, yesterday night I got a little carried away and did a fix for the 
exception message:  [^HDFS-13045.001.patch].
I went with your first proposal there; I had to remember the original path but 
that's fairly simple (didn't check super carefully if there was another place 
with the original path though).

> Currently, Router directly returns exception response from subcluster to 
> client, which may not have the correct error message, especially when the 
> error message containing a path.
> One example, we have a mount path "/a/b" mapped to subclusterA's "/c/d". If 
> user1 does a chown operation on "/a/b", and he doesn't have corresponding 
> privilege, currently the error msg looks like "Permission denied. user=user1 
> is not the owner of inode=/c/d", which may confuse user. Would be better to 
> reverse the path back to original mount path.
