> The {{@KerberosInfo}} annotation specifies the expected server and client
> principals for a given protocol in order to look up the correct principal
> name from the config. The {{NamenodeProtocol}} has the wrong value for the
> client config key. This wasn't noticed because most setups actually use the
> same *value* for for both the NN and 2NN principals ({{hdfs/_HOST@REALM}}),
> in which the {{_HOST}} part gets replaced at run-time. This bug therefore
> only manifests itself on secure setups which explicitly specify the NN and
> 2NN principals.
