Kafka各种报错

1.Replication factor: 2 larger than available brokers: 1

ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication factor: 2 larger than available brokers: 1.

原因创建topic时–replication-factor 2，超过了broker的数量
使用zookeeper可以查看broker的数量

[root@localhost zookeeper-3.4.14]# ./bin/zkCli.sh -server 192.168.230.129
Connecting to 192.168.230.129
[zk: 192.168.230.129(CONNECTED) 2] ls /brokers/ids
[]

2.ERROR Exiting Kafka due to fatal exception (kafka.Kafka$)

找不到properties文件所致，按下面的启动方式即可

[root@localhost local]# cd kafka_2.11-2.3.0/
[root@localhost kafka_2.11-2.3.0]# ./bin/kafka-server-start.sh config/server.properties &

3.Configured broker.id 130 doesn’t match stored broker.id 0 in meta.properties

ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
kafka.common.InconsistentBrokerIdException: Configured broker.id 130 doesn't match stored broker.id 0 in meta.properties. If you moved your data, make sure your configured broker.id matches. If you intend to create a new broker, you should remove all data in your data directories (log.dirs).

原因：本来当做单机服务器，把数据文件删除掉再启动

4.消费者启动报zookeeper is not a recognized option

高版本启动改为 --bootstrap-server

bin/kafka-console-consumer.sh --bootstrap-server 192.168.230.128:2181 --topic MY_TOPIC --from-beginning

5.消费者无法接收到消息

若采用系列教程先单机安装，再集群安装，就会出现这个问题，这是因为broker.id改变的原因。
解决：请关闭kafka、zookeeper，清除data、log文件夹，重启即可，注意zookeeper的data文件夹里myid文件不要删除了！！！
zookeeper的清除可以参考：https://blog.csdn.net/sndayYU/article/details/100537922中报错解决
