> Currently if an application hits NN too hard, RPC requests be in blocking
> state, assuming OS connection doesn't run out. Alternatively RPC or NN can
> throw some well defined exception back to the client based on certain
> policies when it is under heavy load; client will understand such exception
> and do exponential back off, as another implementation of
> RetryInvocationHandler.
