> In HDP 2.3.4.0, the the structure of stored acls for Kafka in zookeeper has
> changed. This means to support upgrade-to or downgrade-from HDP 2.3.4.0 we
> will have to move these stored acls to new format or vice versa.
> Ambari should make the following changes for upgrade/downgrade process of
> Kafka.
> PreReq: Install bits side-by-side
> Steps:
> 1) Stop all Kafka brokers
> 2) Call
> bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer
> --authorizer-properties zookeeper.connect=localhost:2181 --upgradeAcls
> or
> bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer
> --authorizer-properties zookeeper.connect=localhost:2181 --downgradeAcls
> 3) Start all Kafka brokers.
> Example Cases:
> 1) If upgrading from HDP 2.3.0.0 -> 2.3.2.0, we will still stop all Kafka
> brokers since cannot distinguish the version in the single upgrade pack.
> Customers may modify this behavior by editing upgrade-2.3.xml.
> Because the 2.3.4.0 boundary is not crossed, we should not call the migration
> script.
> 2) If upgrading from HDP 2.3.4.0->2.3.5.0, then we will stop all Kafka
> brokers and not call the migration script since not crossing the boundary.
> 3) If upgrading from HDP 2.3.2.0->2.3.5.0, then we will stop all Kafka
> brokers and call the migration script since crossing the boundary. On
> downgrade, we should call the migration script again.
