        I tried to reproduce the bug for two days in order to get some detailed error log. It was hard to reproduce because it occurs rarely. Finally, I grabbed the detail error log!!!

        As my investigation on the state machines, I found the two missed cases:

        KILLED state cannot be transited to T_KILL, T_ATTEMPT_KILLED, or T_ATTEMPT_SUCCEEDED. The states may receive multiple times form workers because workers has some state reporter will periodically send the current task state. They are possible cases in concurrent and distributed cases.

        I think that they should also handle T_ATTEMPT_FAILED in the same way. In sum, SUCCEEDED, FAILED, KILLED should handle T_KILL, T_ATTEMPT_KILLED, T_ATTEMPT_SUCCEEDED, or T_ATTEMPT_FAILED as ignorable state transitions.

        In addition, It's possible if QUERY_ERROR state in Query can take SUBQUERY_COMPLETED because KILLED and FAILED also send SUBQUERY_COMPLETED event to Query. In this case, we have to ignore because Query state is already in QUERY_ERROR.

        I'll submit the patch soon.

        See the below line. I cannot ensure why KillTaskTransition is required in the terminal state KILLED.

        'QueryUnit.java'
        .addTransition(TaskState.KILLED, TaskState.KILLED, TaskEventType.T_ATTEMPT_KILLED, new KillTaskTransition())
        

        If we ensure that KILLED state means QueryUnitAttempt is in KILLED, KillTaskTransition has no effect because TA_KILL event is ignored in the TA_KILLED state.

        'QueryUnitAttempt.java'
        .addTransition(TaskAttemptState.TA_KILLED, TaskAttemptState.TA_KILLED,
                  EnumSet.of(
                      TaskAttemptEventType.TA_LOCAL_KILLED,
                      TaskAttemptEventType.TA_KILL,
                      TaskAttemptEventType.TA_ASSIGNED,
                      TaskAttemptEventType.TA_DONE),
                  new TaskKilledCompleteTransition())
        

        But, I won't modify the state transitions in this release. As far as I know, the current master is already being used in many productions. This change may cause potential side effect. After 0.9.0 release, we can investigate its necessity.
