Kafka到zookeeper命令会产生错误

Question

bin/kafka-topics.sh --create --topic activityTopic --zookeeper localhost:2181/kafka --partitions 1 --replication-factor 1

来自kafka的上述命令会产生错误

任何的想法？

就我而言，问题在于我指定了一个不存在的 kafka chroot。

我发现我们公司的运维团队已经将 kafka chroot 配置为purple-elephants，并配置了这个 chroot 的创建以确保在 kafka 服务重启时。

首先我发出了 asudo service kafka restart并且日志显示 chroot 已创建：

Ensuring chroot '/purple-elephants' exists
Starting Kafka server.                            

然后我简单地发出：

bin/kafka-topics.sh --create --topic activityTopic --zookeeper localhost:2181/purple-elephants --partitions 1 --replication-factor 1
