Comments on the trunk patch:
# NMSimulator: May be change this signature to match AMSimulator and {{throws
Exception}}
{code}
public void middleStep()
throws YarnException, InterruptedException, IOException {
{code}
# Would the following affect performance? Is there a better alternative, may be
wait-notify?
{code}
while (rmAppAttempt.getAppAttemptState() != RMAppAttemptState.LAUNCHED) {
Thread.sleep(50);
{code}
# In the test, remove the space between in {{count --}}. Also, is there a
reason we have to wait for 45 seconds? Can we use a MockClock to speed this
test up?
