MongoDb Debezium - “连接器配置不包含连接器类型”

Question

我正在尝试为 Kafka 和 debezium 做 POC。

我已经启动了 kafka 和 zookeeper，他们正在工作......现在当我尝试加载 kafka-connect 时（我对此有点陌生......）我收到了这个错误，我无法理解我在做什么我做错了。

注意：我已经使用 Debezium 教程 docker 镜像测试了所有这些，但我想从远程服务器连接，我认为在没有 docker 的情况下安装所有东西会更容易使用配置强>

使用以下命令开始连接

./connect-standalone.sh ~/kafka/config/connect-standalone.properties ~/kafka/config/connect-standalone-worker.properties ~/kafka/config/debezium-connector.properties

connect-standalone.properties

bootstrap.servers=localhost:9092
key.converter.schemas.enable=true
value.converter.schemas.enable=true
offset.flush.interval.ms=10000
plugin.path=/home/ubuntu/kafka/plugins

connect-standalone-worker.properties

internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
offset.storage.file.filename=/home/user/offest
value.converter=org.apache.kafka.connect.json.JsonConverter
key.converter=org.apache.kafka.connect.json.JsonConverter

debezium-connector.properties

name=my-connector
connector.class=io.debezium.connector.mongodb.MongoDbConnector
include.schema.changes=false
mongodb.name=mymongo
collection.whitelist=my.collection
tasks.max=1
mongodb.hosts=A.B.C.D:27017

运行连接时我得到以下信息：

Answer 1

connect-standalone.properties 和connect-standalone-worker.properties 需要是一个文件。

错误是说 connect-standalone-worker.properties 没有 connector.class 值（它不应该是因为它是工作属性，而不是连接器）

你尝试运行的命令应该是这样的

connect-standalone worker.properties connector1.properties [connector2.properties ... ]
