> 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.
