我是 Kafka 的新手,正在尝试安装我的 ubuntu 机器 Confluent 控制中心。
这是我遵循的文档:https
:
//docs.confluent.io/platform/current/installation/installing_cp/deb-ubuntu.html 我已经成功地用 3 个代理和 zookeeper 构建了 kafka,但是在 Confluent Control 中存在一些问题中心。
当我开始 conf-cont-center
sudo systemctl start confluent-control-center
/var/log/confluent/control-center.log下的日志说:
The state store, commander, may have migrated to another instance.
