shenhong commented on YARN-1786:
--------------------------------
Here is the code:
{code}
private void sendAppUpdateSavedEvent(RMApp application) {
RMAppEvent event =
new RMAppUpdateSavedEvent(application.getApplicationId(), null);
application.handle(event);
rmDispatcher.await();
}
private void sendAttemptUpdateSavedEvent(RMApp application) {
application.getCurrentAppAttempt().handle(
new RMAppAttemptUpdateSavedEvent(application.getCurrentAppAttempt()
.getAppAttemptId(), null));
}
{code}
At sendAttemptUpdateSavedEvent(), there is no rmDispatcher.await() after handle
an event, it should be changed to
{code}
private void sendAttemptUpdateSavedEvent(RMApp application) {
application.getCurrentAppAttempt().handle(
new RMAppAttemptUpdateSavedEvent(application.getCurrentAppAttempt()
.getAppAttemptId(), null));
rmDispatcher.await();
}
{code}
