    Description

      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.
