在我目前的项目中，我们尝试使用LevelDB复制设置activeMQ群集。我们的配置有一个由三个节点组成的ZooKeeper集合和一个由三个节点组成的ActiveMQ集群。
以下是用于activeMQ的配置:(当然，群集中的每个节点的主机名都不同）
<persistenceAdapter>
<replicatedLevelDB
replicas="3"
bind="tcp://0.0.0.0:0"
hostname="activemq1"
zkAddress="zk1:2181,zk2:2181,zk3:2181"
zkPath="/activemq/leveldb-stores"
/>
</persistenceAdapter>
我们启动了zookeeper的三个实例和activemq的三个实例。我们观察到，动物园管理员领导得到正确选举。但是在activeMQ集群中，Master选举没有发生。通过日志我们了解到zookeeper存在身份验证问题。 （根据日志，我对zookeeper / activemq的了解较少）。在此我粘贴了日志以供参考。

请帮助摆脱这个问题。
如果有人想知道在Kubernetes中部署带有ActiveMQ集群的Zookeeper，请分享您的想法。因为我们正试图在Kubernetes中部署它。
