> Currently RetryInvocation#isRpcInvocation directly uses Proxy#isProxyClass to check RetryInvocation#currentProxy. However, if currentProxy is an instance of ProtocolTranslator (e.g., ClientNamenodeProtocolTranslatorPB), the real dynamically-generated proxy object is contained within currentProxy and needs to be retrieved by calling ProtocolTranslator#getUnderlyingProxyObject.
