问题
I created a cassandra-sink connector after that I made some changes in connector.properties file. After stopping the worker and starting it again, now when I add the connector using:
java -jar kafka-connect-cli-1.0.6-all.jar create cassandra-sink-orders < cassandra-sink-distributed-orders.properties
I get the following error:
Error: the Kafka Connect API returned: Connector cassandra-sink-orders already exists (409)
How can I remove the existing connector?
回答1:
You can use the Kafka Connect REST API, which includes an endpoint for DELETEing a connector.
You might also be interested in Confluent CLI, using which you can simply issue confluent unload foo-connector to delete the connector specified.
回答2:
To delete a connector, you can run:
curl -X DELETE http://localhost:8083/connectors/<connector-name>
