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

             Summary: Wrap the Exception thrown by 
StateMachine#preAppendTransaction as StateMachineException and return the 
exception in RaftClientReply
                 Key: RATIS-62
                 URL: https://issues.apache.org/jira/browse/RATIS-62
             Project: Ratis
          Issue Type: Bug
            Reporter: Jing Zhao


This is a TODO in RaftServerImpl#appendTransaction. The IOException thrown by 
{{applyLog}} is actually from the {{StateMachine#preAppendTransaction}}. This 
exception should be return to RaftClient as a {{StateMachineException}}.
