> The ZkSecurityMigrator tool fails to handle installations where kafka is configured with a zookeeper chroot (as opposed to using /, the default):
>  * ACLs on existing nodes are not modified (they are left world-modifiable)
>  * New nodes created by the tool are created directly under the zookeeper root instead of under the chroot
> The tool does not emit any message, thus the unsuspecting user can only assume everything went well, when in fact it did not and znodes are still not secure:
> kafka_2.12-2.3.0 $ bin/zookeeper-security-migration.sh --zookeeper.acl=secure --zookeeper.connect=localhost:2181
> kafka_2.12-2.3.0 $
> For example, with kafka configured to use /kafka as chroot (zookeeper.connect=localhost:2181/kafka), the following is observed:
>  * Before running the tool
>  ** Zookeeper top-level nodes (all kafka nodes are under /kafka):
> [zk: localhost:2181(CONNECTED) 1] ls /
> [kafka, zookeeper]
>  ** Example node ACL:
> [zk: localhost:2181(CONNECTED) 2] getAcl /kafka/brokers
> 'world,'anyone
> : cdrwa
>  * After running the tool:
>  ** Zookeeper top-level nodes (kafka nodes created by the tool appeared here):
> [zk: localhost:2181(CONNECTED) 3] ls /
> [admin, brokers, cluster, config, controller, controller_epoch, delegation_token, isr_change_notification, kafka, kafka-acl, kafka-acl-changes, kafka-acl-extended, kafka-acl-extended-changes, latest_producer_id_block, log_dir_event_notification, zookeeper]
>  ** Example node ACL:
> [zk: localhost:2181(CONNECTED) 4] getAcl /kafka/brokers
> 'world,'anyone
> : cdrwa
>  ** New node ACL:
> [zk: localhost:2181(CONNECTED) 5] getAcl /brokers
> 'sasl,'kafka
> : cdrwa
> 'world,'anyone
> : r
