> 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.
