Kafka消費時報錯：Producer connection to xxx:9092 unsuccessful

使用kafka消費數據時報Producer錯誤，具體錯誤如下：

kafka.producer.SyncProducer:103 Producer connection to xxx:9092 unsuccessful
java.nio.channels.ClosedByInterruptException

xxx是kafka集群中的某一個節點主機名，雖然kafka消費者沒有配置從此主機上取數據，但必須能夠識別此主機名，因此在本機hosts文件里面修改(C:\Windows\System32\drivers\etc\hosts)，增加域名映射：

192.168.0.120 xxx

問題解決。
