> 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.
