-------------------------------------
Thanx [~hexiaoqiao] for initiative.
I guess we may start with putting up the probable solutions along with the pros
and cons each offers and a basic flow of progression.(Many are here already in
the thread) and collectively start updating that document together extending
each solution, as we progress analyzing here.
Let me know for any help in this.:)

> 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.
