> When trying to add a SCRAM user in ZooKeeper without having ever starting
> Kafka, the kafka-configs tool does not handle it well. This is a common use
> case because starting a new cluster where you want SCRAM for inter broker
> communication would generally result in seeing this problem. Today, the
> workaround is to start Kafka, add the user, then restart Kafka. Here's how to
> reproduce:
> 1) Start ZooKeeper
> 2) Run
> {code}
> bin/kafka-configs --zookeeper localhost:2181 --alter --add-config
> 'SCRAM-SHA-256=[iterations=8192,password=broker_pwd],SCRAM-SHA-512=[password=broker_pwd]'
> --entity-type users --entity-name broker
> {code}
> This will result in:
> {code}
> bin/kafka-configs --zookeeper localhost:2181 --alter --add-config
> 'SCRAM-SHA-256=[iterations=8192,password=broker_pwd],SCRAM-SHA-512=[password=broker_pwd]'
> --entity-type users --entity-name broker

> The command doesn't appear to fail but it does throw an exception. The return
> code of the script is still 0 and the user is created in ZooKeeper but this
> should be cleaned up since it's misleading.
