> Currently in ActiveStandbyElector, when its zookeeper client cannot
> successfully communicate with ZooKeeper service, the retry number is hard
> coded to 3 (ActiveStandbyElector#NUM_RETRIES). After retrying 3 times a fatal
> error will be thrown and the ZKFC will quit. It will be better to make the
> retry times configurable.
