Review request for Tajo.
Bugs: TAJO-819
https://issues.apache.org/jira/browse/TAJO-819
Repository: tajo
Description
-------
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.
