> There are two types of killing queries. First is that QueryMaster cancel
> QueryUnitAttempt before QueryUnitAttempt be passed to TajoWorker. Second is
> that TajoWorker cancel running QueryUnitAttempt.
> If QueryMaster cancel QueryUnitAttempts, it will be stopped. But
> unfortunately, at nearly the same time, a few QueryUnitAttempts can be passed
> to TajoWorker. And these never will be stopped because it can't find valid
> state for state machines.
