我有一个zookeeper, 2个集群代理和2个集群连接，集群连接工作良好，完全覆盖彼此。但是当其中一个代理节点发生故障时，连接器将打印无法连接到代理并且连接器无法正常工作。我检查了连接器主题，但问题发生后没有推它。

您的Connect主题复制因素只有一个。
CONNECT_CONFIG_STORAGE_TOPIC: docker-connect-storage # renamed - it is not only for mysql
CONNECT_CONFIG_STORAGE_REPLICATION_FACTOR: 1
CONNECT_OFFSET_STORAGE_TOPIC: docker-connect-offsets
CONNECT_OFFSET_STORAGE_REPLICATION_FACTOR: 1
CONNECT_STATUS_STORAGE_TOPIC: docker-connect-status
CONNECT_STATUS_STORAGE_REPLICATION_FACTOR: 1
如果承载这些主题的代理崩溃，那么您应该期望Connect也崩溃/停止工作
