无法加载kafka connect debezium mongodb连接器

Question

我有一个现有的2 kafka服务器加载mysql连接器。它起作用了。此外，我需要添加MongoDB连接器。我已经在我的Kafka服务器(Centos7)上安装了confluent-schema-registry，它可以工作，我停止/启动/重新启动，看起来没有任何问题。我已经在这里下载并解压了debezium Mongo插件；/usr/connector/plugins/debezium-connector-mongodb/

我已经编辑了/etc/schema-registry/connect-avro-distributed.properties，并修改了以下代码行：

plugin.path=share/java,/usr/connector/plugins
bootstrap.servers=kafka3:9092,kafka4:9092
rest.host.name=kafka3
rest.port=8084
rest.advertised.host.name=kafka3
rest.advertised.port=8084

我运行schema-registry，一切正常，插件已加载。我想通过REST加载连接器，如下所示：

curl -i -X POST -H "Accept:application/json" \
    -H  "Content-Type:application/json" http://kafka3:8084/connectors/ \
    -d  '{
  "name": "mongodb-connector",
  "config": {
    "connector.class": "io.debezium.connector.mongodb.MongoDbConnector",
    "mongodb.hosts": "shardreplica01/mongodb-shardsvr1:27017,shardreplica01/mongodb-shardsvr2:27017",
    "mongodb.name": "mongoreplica",
    "mongodb.user": "debezium",
    "mongodb.password": "******",
    "database.whitelist": "mongo[.]*",
  }
}'

...but显示以下错误，无法加载连接器：

HTTP/1.1 500 Internal Server Error
Date: Tue, 21 Jan 2020 20:04:13 GMT
Content-Type: application/json
Content-Length: 350

{"error_code":500,"message":"Unexpected character ('}' (code 125)): was expecting double-quote to start field name\n at [Source: (org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream); line: 9, column: 27] (through reference chain: org.apache.kafka.connect.runtime.rest.entities.CreateConnectorRequest[\"config\"])"}

我需要帮助；我遗漏了什么？

谢谢

您的JSON无效-您有一个尾随逗号：

"database.whitelist": "mongo[.]*",
                                 ^
                                 |
                    HERE --------+
