Once the Zookeeper quorum is down, brokers could result in a bad state and
could not normally serve client requests, etc. Although when Zookeeper quorum
recovers, the Kafka brokers should be able to resume to normal state
automatically, _there are still a few +corner cases+ the they cannot and a hard
kill-and-recovery is required to bring it back to normal_. Hence it is
recommended to closely monitor your zookeeper cluster and provision it so that
it is performant.

As ZK quorum failures are inevitable (due to rolling upgrades of ZK, leader
hardware failure, etc), it would be great to identify the corner cases (if they
still exist) and fix them if necessary.
