NiFi 1.11.4 with Zookeeper ACL enabled: failed to set state for components

[pa...@gmail.com]

Hello!

I try to set a secure connection to Zookeeper with ACL enabled.

Add to Zookeeper JAVA_OPTS
-Djava.security.auth.login.config={{ zookeeper_config_dir }}/jaas.conf

jaas.conf
```
QuorumServer {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       user_zk="{{ zookeeper_security_quorumserver_user }}";
};

QuorumLearner {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       username="{{ zookeeper_security_quorumlearner_user }}"
       password="{{ zookeeper_security_quorumlearner_password }}";
};

Server {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       user_super="{{ zookeeper_security_super_password }}";
};
```

Configure NiFi to use secured Zookeeper by setting property Access 
Control at state-management.xml to CreatorOnly and add jaas.conf

bootstrap.conf
```
java.arg.18=-Djava.security.auth.login.config={{ nifi_conf_dir 
}}/jaas.conf
java.arg.19=-Dzookeeper.sasl.client.username={{ 
nifi_zookeeper_security_username }}
```

nifi.properties
```
nifi.zookeeper.auth.type=sasl
```

jaas.conf
```
Client {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       username="{{ nifi_zookeeper_security_username }}"
       password="{{ nifi_zookeeper_security_password }}";
};
```

Apache Nifi Cluster is starting, all seems OK with cluster (znode 
/nifi/ was creating with ACLs, but a few moments later users claims 
about error on processors querydbtable:
```
Failed to set cluster-wide state in ZooKeeper for component with ID
java.io.IOException: Failed to set cluster-wide state in ZooKeeper for 
component with ID
```

I can see that with CreatorOnly enabled and jaas configuration NiFi 
didnt create /nifi/components or set right ACL for root node
Here we have a working NiFi Cluster which cannot save processors state 
at zookeeper because of no /nifi/components.

What did I miss?
