Andrew Wang updated HADOOP-10584:

Adding a 3.x fix version for tracking, good bug to get fixed?

> 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.
