Jing Zhao updated HADOOP-9786:
------------------------------
Description: Currently RetryInvocationHandler#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. (was: Currently

to be retrieved by calling ProtocolTranslator#getUnderlyingProxyObject.)
