增加kafka节点,对原有节点的顺序做了调整,报错如下:

cxid:0x2a zxid:0x1e txntype:-1 reqpath:n/a Error Path:/brokers/ids Error:KeeperErrorCode = NodeExists for /brokers/ids (org.apache.zookeeper.server.PrepRequestProcessor)

检查配置server.properties

# cat /bigdata/kafka/config/server.properties
broker.id=2  //id重复了,改一个kafka集群中,没有id

重启kafka后,上面的报错没有了,但又出了新的报错

[2019-10-16 11:30:14,977] ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
kafka.common.InconsistentBrokerIdException: Configured broker.id 2 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).

解决办法:

# vim /bigdata/kafka/data/meta.properties
broker.id=2  //根server.properties一样
