-----------------------------------

             Summary: Properly unpack thrown exceptions in RPC methods
                 Key: FLINK-5239
                 URL: https://issues.apache.org/jira/browse/FLINK-5239
             Project: Flink
          Issue Type: Sub-task
          Components: Distributed Coordination
         Environment: {{flip-6}} feature branch.
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen


When an RPC invocation fails, the exception is an {{InvocationTargetException}} that contains the actual exception.

We should report the actual exception to the sender, rather than the {{InvocationTargetException}}.
