示例1: isFinished
@Override
public boolean isFinished() {
readLock.lock();
try {
// TODO: Use stateMachine level method?
return (getInternalState() == TaskStateInternal.SUCCEEDED ||
getInternalState() == TaskStateInternal.FAILED ||
getInternalState() == TaskStateInternal.KILLED);
} finally {
readLock.unlock();
}
}
示例2: transition
@Override
public TaskStateInternal transition(TaskImpl task, TaskEvent event) {
TaskTAttemptEvent castEvent = (TaskTAttemptEvent) event;
if (task.getInternalState() == TaskStateInternal.SUCCEEDED &&
!castEvent.getTaskAttemptID().equals(task.successfulAttempt)) {
// don't allow a different task attempt to override a previous
// succeeded state
task.finishedAttempts.add(castEvent.getTaskAttemptID());
task.inProgressAttempts.remove(castEvent.getTaskAttemptID());
return TaskStateInternal.SUCCEEDED;
}
// a successful REDUCE task should not be overridden
//TODO: consider moving it to MapTaskImpl
if (!TaskType.MAP.equals(task.getType())) {
LOG.error("Unexpected event for REDUCE task " + event.getType());
task.internalError(event.getType());
}
// tell the job about the rescheduling
task.eventHandler.handle(
new JobMapTaskRescheduledEvent(task.taskId));
// super.transition is mostly coded for the case where an
// UNcompleted task failed. When a COMPLETED task retroactively
// fails, we have to let AttemptFailedTransition.transition
// believe that there's no redundancy.
unSucceed(task);
// fake increase in Uncomplete attempts for super.transition
task.inProgressAttempts.add(castEvent.getTaskAttemptID());
return super.transition(task, event);
