用kfafka命令：./kafka-server-start.sh ../config/server.properties &啟動時報以下錯誤：

[2016-04-27 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)

解決辦法是：

複製kafka/config路徑下的server.properties檔案為：server-1.properties和server-2.properties

並修改這兩個檔案的配置項：

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在這三個配置項中都不一樣。

修改完成之後啟動：

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

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

./kafka-server-start.sh ../config/server-2.properties &

前一個啟動可能還會報這個錯，繼續啟動，都啟動成功之後這個問題就解決了！

good luck！
