Thanks for bringing this improvement. Sorry I do not receive discussion in
mail-list and reply here directly.
I am not sure if it is the best solution to expose namespace id to client
which will confuse the end-user in my opinion.
`If we are adding new protocols, maybe we can add "renewLease(String
clientName, String path)" and let Router do the resolve from path to namespace.`
In my practice, I think `path` will be the good choice here. Strong +1. And
router could resolve it which keep the same logic for other interface. But the
bad news is that it will increase the invoke interface times. Anyway, I think
this solution will not break anything.

> Currently renewLease() against a router will make fan-out to all the
> NameNodes. Since renewLease() call is so frequent and if one of the NameNodes
> are slow, then eventually the router queues are blocked by all renewLease()
> and cause router degradation.
> We will make a change in the client side to keep track of NameNode Id in
> additional to current fileId so routers understand which NameNodes the client
> is renewing lease against.
