Kafka 오류 - 미해결

consumer로 접속시 밀리초 단위로 마구 나오는 오류

bash-5.1# kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic loan_request
이렇게 접속하면 이것들이 마구 나옴

consumer main application을 실행시키면

이런오류가 마구 난다.

 

처음에는 kafka 알려진 호스트가 없습니다 이런 오류가 나서 docker-compose.yml 의

KAFKA_ADVERTISED_HOST_NAME: 127.0.0.1

이 부분을 kafka -> 127.0.0.1로 바꿔주었다.

 

그랬더니 일단 이렇게 된 것 !

https://stackoverflow.com/questions/53571823/why-could-kafka-warn-partitions-have-leader-brokers-without-a-matching-listener

 

Why could Kafka warn "partitions have leader brokers without a matching listener"?

I'm trying to get Kafka to work on docker-compose for the first time. The application runs fine without docker. But on docker, I get the error as described below. Any reason why Kafka would throw t...

stackoverflow.com

여기에서 KAFKA_ADVERTISED_HOST_NAME 대신 KAFKA_ADVERTISED_LISTENERS이걸 쓰라고 해서 바꿔줬다.

KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:29092,PLAINTEXT_HOST://localhost:9092

앞에 kafka는 hostname이고 localhost는 호스트 장비 IP의미 

Docker 네트워크 내부에서 접근할 주소와 외부에서 접근할 주소를 기입해줌.

이것만 넣으면 kafka가 켜졌다 바로 종료됨

 

고쳐주고 consumer 실행시 이번엔 아래 코드가 반복되다

2023-10-16 22:05:20.756  WARN 2168 --- [ntainer#0-0-C-1] org.apache.kafka.clients.NetworkClient   : [Consumer clientId=consumer-fintech-1, groupId=fintech] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available.

이 부분이 나오고 종료돼버림

UnknownHostException 
kafka 모듈 작성 후 Test 시 발생한 오류
$ curl --location --request POST 'http://localhost:8080/fintech/api/v1/request' 
--header 'Content-Type: application/json' 
--data-raw 
'{

}'

userKey 값이 리턴되어야 하는데 PostMan에서는 잘 되는데 

터미널에서 하면 안 된다 대체 왜 ????????????? 그리고 ApiApplication에서는 아래와 같은 오류가 계속 반복해서 뜬다.

docker desktop - kafka - files - opt - kafka_2.12-2.5.0 - config - server.properties에

31번째 줄 주석을 해제해주라는데 나는 이미 해제가 되어있었음

 

# kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic loan_request

이렇게 consume을 해봐도 마찬가지 ... 

[2023-10-16 16:15:18,136] WARN [Consumer clientId=consumer-console-consumer-31017-1, groupId=console-consumer-31017] 1 partitions have leader brokers without a matching listener, including [loan_request-0] (org.apache.kafka.clients.NetworkClient)

저 server.properties에 0.0.0.0을 localhost로 바꿔주었음

그래도 동일한 오류...

 

아직 미해결 ㅠ
