Thanks [~sandflee] for raising this and for the patch.

Yup, it is definitely useful to find out exactly which events are backed up in 
the queue.
In our production clusters, we do have a patch this is similar to what you have 
put up. One suggestion though: instead of iterating an creating a new map 
everytime (not to mention the performance cost of iterating thru the queue 
everytime), what we do is to keep a ConcurrentHashMap as a 
persistent field in the Dispatcher. We then update the counter (or 
insert/remove an entry if required) everytime an event is inserted or removed 
from the queue. And we just dump the map if the total size of the queue is 
greater than some value. 

Additionally, it would also be useful to dump the last event that was 
dispatched - this can give a hint of which handler potentially caused the backup

Thanks [~miklos.szeg...@cloudera.com] for your detailed reply, seems no much  
necessary to add a UT :(

Thank you for the quick reply [~sandflee]!

It is really optional. I was wondering if we could test at least whether the 
log has arrived. I could come up with a draft but it uses reflection. It is up 
to you, whether you want to do something similar.
{code}
Log log = Mockito.mock(Log.class);
AsyncDispatcher dispatcher = new AsyncDispatcher();

Field logger = AsyncDispatcher.class.getDeclaredField("LOG");
logger.setAccessible(true);
Field modifiers = Field.class.getDeclaredField("modifiers");
modifiers.setAccessible(true);
modifiers.setInt(logger, logger.getModifiers() & ~Modifier.FINAL );
Object oldLog = logger.get(null);

try {
  logger.set(null, log);

  dispatcher.init(new Configuration());
  dispatcher.register(TestEnum.class, new EventHandler() {
@Override
public void handle(Event event) {
  try {
Thread.sleep(1500); // As long as 1 events queued
  } catch (InterruptedException e) {
  }
}
  });
  dispatcher.start();
  for (int i = 0; i < 1; ++i) {
dispatcher.getEventHandler().handle(new 
TestEvent(TestEnum.TestEventType));
  }
  Mockito.verify(log, Mockito.atLeastOnce()).info("event type: 
TestEventType, num: 5000, capacity: 1.0");
  dispatcher.stop();
} finally {
  //... restore logger object
}
{code}

Thank you for the patch [~sandflee]!

I see a missing space in the patch. Also, it would be nice to have a unit test 
for printEventQueueInfo.

Jun Gong commented on YARN-5276:


I think it might be enough to add some debug information. When the size of 
event queue is increasing, we could set its log level to DEBUG on the fly to 
see what is happening.

Yes, 5K would be better I think. One nit is give space after comma in log 
message.

thanks [~rohithsharma], agree, and I think it's reasonable to keep INFO level, 
since most clusters are at this level. Any  dividing factor  suggest? 5 ?

Just caught up with this issue. This is really required for debugging loaded 
dispatcher. 
Overall patch reasonable to me. One thing I observe is logging is in INFO. But 
in large cluster 1K 2K 3K events are so common in fluctuation that printing for 
every modulus(%) 1K  does not reasonable I feel. Either we need to change to 
DEBUG or need to increase dividing factor greater than 1K. Thoughts?
