Subject Kafka upgrade from 0.8.0 to
Date Fri, 11 Nov 2016 07:43:19 GMT

For a rolling upgrade, Kafka suggest upgrade the brokers one at a time (shut down the broker,
update the code, and restart it) to avoid downtime during the upgrade.
Usually, there is one zookeeper point to some brokers in a Kafka cluster, if the zookeeper
should be upgraded also? If so, how to avoid downtime during zookeeper upgrade? Thanks!

Best Regards
