[~elgoiri] I modify the code , please take a look.
{quote}
I think we should make a function to add to the favoredNodes and add a few unit tests just for it
{quote}
Done
{quote}
 and a full unit test that actually involves a Router and a Namenode.
{quote}
It's not so easy to verify the locality, think about later.
{quote}
We should do new ArrayList<String>(favoredNodes.length + 1);.
{quote}
Fixed
Upload v003 patch

> 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.
