阿里云上部署kafka--遇到的坑

kafka文档
kafka下载包
kafka-manager 后台管理系统

阿里云防火墙关闭,并且配置规则。不然会导致访问不到服务。

问题一:
Caused by: java.net.UnknownHostException: iZuf68tztea6l5ccdz7wemZ: iZuf68tztea6l5ccdz7wemZ: Name or service not known

vi /etc/hosts
127.0.0.1 iZuf68tztea6l5ccdz7wemZ

iZuf68tztea6l5ccdz7wemZ 自己的主机名

问题二:
ERROR Error when sending message to topic test with key: null, value: 3 by
tes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.TimeoutException: Batch containing 2 record(s) expired due to timeout
