【问题描述】：
我们有 Cloudera Express 5.11.0 集群，我正在尝试将 Kafka 3.0 作为服务添加到 cloudera 管理器中，但我收到错误消息，它无法在所有节点上启动代理，但我没有看到任何错误。我下载了percel并分发激活成功。
我有几个问题：
-
我应该在 ZooKeeper Root 中设置什么值？这是我应该决定的还是取决于动物园管理员的安装？我看到最常见的是/kafka，所以我把它设置为/kafka。
-
我们的 zookeeper 作为独立运行并收到有关最大请求延迟的警报，可能已连接？
-
在将 Kafka 添加为服务的第 4 步中，在节点中启动代理失败，我不确定是什么错误。我看到了一些关于 OutOfMemory 的消息，但我不确定它是检查还是错误。
我将添加我找到的日志的最后几行：
标准输出：
