Below code already gets the RMApp instance and then send an event to RMApp to
update the collector address. Instead of updating via event, it could just
update via a method of RMApp. This also avoids state-machine changes i
{code}
} else {
String previousCollectorAddr = rmApp.getCollectorAddr();
if (previousCollectorAddr == null
|| !previousCollectorAddr.equals(collectorAddr)) {
// sending collector update event.
RMAppCollectorUpdateEvent event =
new RMAppCollectorUpdateEvent(appId, collectorAddr);
rmContext.getDispatcher().getEventHandler().handle(event);
}
}
