一、问题

用kfafka命令:./kafka-server-start.sh ../config/server.properties &启动时报以下错误:

[2018-01-28 21:54:44,745] ERROR [KafkaApi-100] error when handling request Name: TopicMetadataRequest; Version: 0; CorrelationId: 1496; ClientId: producer-1; Topics: Interation,Booksheet (kafka.server.KafkaApis)

二、解决方案

解决办法是:

复制kafka/config路径下的server.properties文件为:server-1.properties和server-2.properties

并修改这三个文件的配置项:

server.properties

broker.id=0
port=9092
log.dir=/tmp/kafka-logs-0
host.name=localhost


server-1.properties

broker.id=1
port=9093 
log.dir=/tmp/kafka-logs-1
host.name=localhost

server-2.properties

broker.id=2
port=9094
log.dir=/tmp/kafka-logs-2
host.name=localhost
broker.id、port、log.dir在这三个配置项中都不一样。

修改完成之后启动:

nohup ./kafka-server-start.sh ../config/server.properties &

nohup ./kafka-server-start.sh ../config/server-1.properties &

nohup ./kafka-server-start.sh ../config/server-2.properties &
前一个启动可能还会报这个错,继续启动,都启动成功之后这个问题就解决了!
