什么会导致这个 debezium kafka 连接器错误？

Question

我正在寻找连接 mysql --> debezium --> kafka（融合云）。我想知道是否有人可以帮助我解决这个错误消息：

Failed to find any class that implements Connector and which name matches io.debezium.connector.mysql.MySqlConnector.

我的 kafka worker 文件中有 debezium 的 jar 文件：

plugin.path=/home/ec2-user/kafka/plugins

插件文件夹内容如下：

-antlr4-运行time-4.7.2.jar

-debezium-api-1.5.3.Final.jar

-debezium-连接器-mysql-1.5.3.Final.jar

-debezium-core-1.5.3.Final.jar

-debezium-ddl-parser-1.5.3.Final.jar

-failureaccess-1.0.1.jar

-guava-30.0-jre.jar

-mysql-binlog-connector-java-0.25.1.jar

-mysql-连接器-java-8.0.21.jar

当我启动分发器时，我看到添加了插件：

但是，当我运行我的 curl 命令时：

curl -s -X POST -H 'Content-Type: application/json' --data @debe-connector.json http://localhost:8083/connectors -v

我收到错误：

Failed to find any class that implements Connector and which name matches io.debezium.connector.mysql.MySqlConnector.

知道我可能遗漏了什么吗？

谢谢，

Answer 1

您需要将debezium mysql connector的所有jar文件放在一个目录

中

/home/ec2-user/kafka/plugins/debezium-connector-mysql

而不是刚好低于

/home/ec2-user/kafka/plugins

Answer 2

可以使用curl命令

curl -X GET http://localhost:8083/connector-plugins

查看正确安装了哪些插件。如果此处未列出 debezium，则表示安装存在问题。您可能需要检查文件权限。
