I am trying to do a POC for Kafka and debezium.
I have started kafka and zookeeper and they are working... now when I try to load kafka-connect (I am kind of new to this...) I get this error that I just can't understand what I am doing wrong.
Note: I have tested all of this with the Debezium tutorial docker images, but I would like to connect from a remote server and I thought it would be easier to install everything without docker to play with the configuration
starting the connect with the following command
./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
I get the following when running the connect:

connect-standalone.properties and connect-standalone-worker.properties need to be one file.
The error is saying that connect-standalone-worker.properties has no connector.class value (which it shouldn't because it's the worker properties, not a connector)
The command you're trying to run should look like
connect-standalone worker.properties connector1.properties [connector2.properties ... ]
