[jira] [Created] (RATIS-614) Raft leader should use state machine's last applied index for LeaderNotReady exception

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

             Summary: Raft leader should use state machine's last applied index for LeaderNotReady exception
                 Key: RATIS-614
                 URL: https://issues.apache.org/jira/browse/RATIS-614
             Project: Ratis
          Issue Type: Bug
            Reporter: Lokesh Jain
            Assignee: Lokesh Jain


Currently Raft leader uses the StateMachineUpdater's lastAppliedIndex to determine if leader is ready to take requests. It should rather use StateMachine's lastAppliedTermIndex because it denotes the index till which the transactions have already been applied whereas StateMachineUpdater's lastAppliedIndex denotes the index till which the applyTransaction call has already been made.
