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

創建 Topic 時出現該錯誤，創建命令：

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

 

錯誤如下;

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$)

 

錯誤原因：出現的問題是因為Kafka Broker 在 zookeeper 存儲的路徑並不是根目錄，而是 /kafka 路徑

可以啟動zookeeper得客戶端查看kafka 的Broker路徑：

$ bin/zkCli.sh

#進入客戶端查看路徑詳情
$ ls -R /

因此，修改創建 Topic 的指令：

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