--------------------------------------------------

Does seem critical to me, but haven't seen any activity in a while. [~kasha] / [~xgong], can one of you comment on a possible fix? If it's uncertain, I'd like to move this to 2.7.2. Tx.

> ActiveStandbyElector retries operations for a few times. If the ZK quorum itself is down, it goes down and the daemons will have to be brought up again. 
> Instead, it should log the fact that it is unable to talk to ZK, call becomeStandby on its client, and continue to attempt connecting to ZK.
