> With the new RPCv9, NN RPC server can be bound to multiple IP addresses and 
> serve clients connecting to different addressed using the same SPN. But the 
> only way to have NN bind to multiple addresses is to set its RPC address to 
> 0.0.0.0. This does not work well with HA especially when name nodes share the 
> same config. 
> I propose a new option for NN rpc server to bind to all interfaces, 
> independent of the rpc address configuration.
