{quote}Fake client hostname: I don't quite get this one.{quote}
It is possible to construct fake client hostname no matter which solution we
choice between changing {{ClientProtocol}} and {{RPC Framework}}, since
ClientProtocol interface or Protocbuffer are totally open to client, and client
could input arbitrary hostname as itself. However I believe it's under control
and no more security risk even if it is fake hostname in generally. Just point
the leak.
Totally, I am not very clear preference for changing {{ClientProtocol}} or
{{RPC}} layer now. I believe there may be less works If we adopt to changing
{{RPC/IPC}} layer solution.
My suggestion is we should vote one solution and catch up this feature to
native as soon as possible. We still have chances to optimize it latter. This
is just my personal opinion.:)

> When execute a put operation via router, the NameNode will choose block
> location for the router, not for the real client. This will affect the file's
> locality.
> I think on both NameNode and Router, we should add a new addBlock method, or
> add a parameter for the current addBlock method, to pass the real client
> information.
