错误示例
[root@localhost kafka_2.12-2.5.0]# kafka-topics.sh --zookeeper 127.0.0.1:2181 --create --topic test2 --partitions 2 --replication-factor 2 Error while executing topic command : Replication factor: 2 larger than available brokers: 1. [2020-10-22 15:12:09,776] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication factor: 2 larger than available brokers: 1. (kafka.admin.TopicCommand$)百度错误原因,得到以下几点:
kafka没有启动这个也是访问量最高的,但是我感觉他文章写的像屎一般完全不容易看,地址:https://blog.csdn.net/duyenson/article/details/103356480,大体意思是你的zookeeper.connect参数写错了,多了个zookeeper的路径啥的.最后也是我遇到的一种,kafka是单机的,但是创建的时候副本数replication设置了2,副本是不能再一台主机的,所以我这的问题是副本数大于集群节点数.解决过程:
先是百度,没什么收获,然后我改了下zookeeper连接地址,将本级IP改成了127.0.0.1,再次执行提示了:
[root@localhost kafka_2.12-2.5.0]# kafka-topics.sh --zookeeper 127.0.0.1:2181 --create --topic hadoop --partitions 2 --replication-factor 2 Error while executing topic command : Replication factor: 2 larger than available brokers: 1. [2020-10-22 15:10:08,854] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication factor: 2 larger than available brokers: 1. (kafka.admin.TopicCommand$) [root@localhost kafka_2.12-2.5.0]# kafka-topics.sh --zookeeper 127.0.0.1:2181 --create --topic hadoop --partitions 2 --replication-factor 1 Created topic hadoop.他比之前多了一行!
但是报错是相同的,再次百度,借鉴于大佬的https://blog.csdn.net/WZY_snail/article/details/105346297这篇文章,我将副本数改成了1,解决.再次将地址改回去,副本数2创建失败,就提示了上面的错误.
