我已经试了两个星期了,我在不同的机器上运行kafka集群,而不是连接节点。我无法使连接正常运行。我可以读写Kafka没有问题。Zookeeper似乎运转良好。
我启动连接:
$ bin/connect-distributed connect-distributed.properties
connect不断循环此错误:

以下是我的connect-distributed.properties的外观:

将所有kafka代理的主机名添加到/etc/hosts文件中,然后重试

我也有同样的问题。。。Kafka解决了我的问题。
执行后:
使我的日志在不到10秒内恢复正常:

在go中编写了一个连接器之后,我遇到了同样的问题。我被迫自己解决。
当连接器连接到Kafka时,它会自动写入主题和
__offset_topics
. 当连接器崩溃时,它作为协调器在这些表中留下自己的痕迹。当新连接器启动时,它会在表中找到记录并尝试与协调器通信。协调器无法响应,连接器无法工作。你可以用两种方法来解决这个问题,删除所有的主题(
connect-configs
,connect-offsets
,connect-status
,__offset_topics
)然后重新启动群集。另一种方法是从主题中删除协调器,我目前不确定如何执行。
