> Now, in {{RecoverableZooKeeper}}, the retry backoff sleep time grow 
> exponentially, but it doesn't have any up limit. It directly lead to a long 
> long recovery time after Zookeeper going down for some while and come back.
> A case of damage done by high sleep time:
> If the server hosting zookeeper is disk full, the zookeeper quorum won't 
> really went down but reject all write request. So at HBase side, new zk write 
> request will suffers from exception and retry. But connection remains so the 
> session won't timeout. When disk full situation have been resolved, the 
> zookeeper quorum can work normally again. But the very high sleep time cause 
> some module of RegionServer/HMaster will still sleep for a long time(for 
> example, the balancer) before working.
