kafka报错——Error while executing topic command : Replication factor: 3 larger than available brokers: 0.

创建 Topic 时出现该错误，创建命令：

[hw@node01 bin]$ ./kafka-topics.sh --create --topic first --zookeeper node01:2181 --partitions 3 --replication-factor 1

 

错误如下;

Error while executing topic command : Replication factor: 3 larger than available brokers: 0.
[2022-02-26 15:55:45,948] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication factor: 3 larger than available brokers: 0.
 (kafka.admin.TopicCommand$)

 

错误原因：出现的问题是因为Kafka Broker 在 zookeeper 存储的路径并不是根目录，而是 /kafka 路径

可以启动zookeeper得客户端查看kafka 的Broker路径：

$ bin/zkCli.sh

#进入客户端查看路径详情
$ ls -R /

因此，修改创建 Topic 的指令：

[hw@node01 bin]$ ./kafka-topics.sh --create --topic first --zookeeper node01:2181/kafka --partitions 1 --replication-factor 3
