Kafka消费时报错：Producer connection to xxx:9092 unsuccessful

使用kafka消费数据时报Producer错误，具体错误如下：

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

xxx是kafka集群中的某一个节点主机名，虽然kafka消费者没有配置从此主机上取数据，但必须能够识别此主机名，因此在本机hosts文件里面修改(C:\Windows\System32\drivers\etc\hosts)，增加域名映射：

192.168.0.120 xxx

问题解决。
