融合控制中心未拦截流

标签： postgresql apache-kafka apache-kafka-connect confluent debezium

我正在使用带有Kafka流的CCC，该流由Debezium的Postgres Connector填充。

我正在使用以下docker-compose.yml：

version: '2'

我已将Postgres Connector映射到Kafka Connect（通过Compose中的volumes），并且在创建新的Source Connector时可以在CCC中看到它。

当我创建源连接器时，我可以看到指示创建此连接器主题的日志消息。我还在CCC的“连接”区域中看到了该主题。我还可以看到Connect可以通过此连接器向Postgres进行身份验证。

当我对在连接器中指定的表进行更改时，我看到Kafka（我有3个集群）弄清楚谁将存储此消息。意思是，Postgres tx日志响应于我的更改创建了一条有关相应主题的消息，因此数据库，连接器和Kafka正常工作。

但是，无论我做什么，我都无法在Data Streams 或System Health（> Topics和> Brokers区域中都不显示此事件） （编辑：现在可以使用。数据流仍然无效）。

我对发生的事情不知所措。我得到的唯一指示是初始消息说

  

仔细检查以查看是否对为群集控制中心生产或使用群集的任何客户端正确配置了监视拦截器

我的印象是，这实质上意味着我的Control Center容器配置有我上面粘贴的*_INTERCEPTOR_CLASSES。我点击了此消息上的链接，该链接将您带到其文档站点，该站点检查要检查提供kafka数据的Web服务的响应。正如他们的文档所建议的那样，我得到的响应仅为{}，表明Kafka表示没有数据。但这确实可以。

是否要说我还需要以某种方式将这些拦截器配置到连接器中？我不知道为任何消费者/生产者提供监视拦截器是什么意思-我还没有任何原始的Java消费者/生产者...目前只有源连接器。

如果有必要，我的连接器配置如下（通过CCC UI创建）：

{
  "database.server.name": "my-namespace",
  "database.dbname": "my-database",
  "database.hostname": "my-hostname",
  "database.port": "5432",
  "database.user": "admin",
  "schema.whitelist": "public",
  "table.whitelist": "my-database.my-table",
  "connector.class": "io.debezium.connector.postgresql.PostgresConnector",
  "name": "my-connector",
  "database.password": "its correct"
}

启动所有服务时，我在我认为可能感兴趣的相应日志中看到以下内容（以下没有特殊顺序）：

control-center     | 2018-09-17T20:45:02.748463792Z     interceptor.classes = []

感谢您的帮助。谢谢！
