ProtobufRPCEngine client side exception mechanism is not consistent with
WritableRpcEngine
------------------------------------------------------------------------------------------
Key: HADOOP-7897
URL: https://issues.apache.org/jira/browse/HADOOP-7897
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 0.24.0
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Fix For: 0.24.0
In ProtobufRpcEngine the client side exceptions are wrapped in
RpcClientException. The RpcClientException is used to create RemoteException
which is set as cause in the thrown ServiceException. However WritableRpcEngine
throws the client encountered exception as is. This difference in behavior
causes, many tests to fail in the existing unit tests, which expect the client
invoker() to thrown the exception as is. This jira makes the ProtobufRpcEngine
behavior consistent with that of WritableRpcEngine.
