Description of PR
Now when Observer NN is used, if the stateid is delayed , the call will be requeued into callqueue. If EditLogTailer is broken or something else wrong , the call will be requeued again and again.
So Observer should throw ObserverRetryOnActiveException if stateid is always delayed with Active Namenode for a configured time.
