안녕하세요, 빅디님! 차근차근 따라하려고 하는데.. 한 강 한강 막히고 있습니다.. 하둡과 주키퍼 명령 사용해보기 강의보며 실습중인데, 명령어가 먹히지 않습니다.. 연결이 안되는 에러로 보여서 클라우데라 접속하려고 했더니 클라우데라도 접속이 안됩니다. 빅데이터 클러스터 구성 4 강의 까지는 다 따라한 상태입니다. 클라우데라 접속해서 하둡과 주키퍼 설치까지 완료하였고 일주일? 지난 후 다시 접속해서 그 이후 과정 따라하려고 하니 접속에러 & 연결에러가 뜨고 있습니다............ ㅠㅠ 막힘없이 쭉쭉 나가고 싶은데 ,, 대체 무슨문제일까요 ? 저 같은 에러를 경험하신 분이 있을까 싶어 이전 질문글을 살펴봤는데 파일럿 PC의 용량이 존재해야 한다고 하여 정리도 하고, 실행했습니다. 많이 사용하긴 했지만 212GB가 남아있는 상황입니다.. 실습 쭉 따라하고 싶습니다..빅디님.....ㅠ_ㅠ!! ++ 로그 확인 이상 없음. (참고로 모바텀을 사용하고 있어서 파일질라는 사용안하고 모바텀으로 바로 Sample.txt -> /home/bigdata 로 올렸습니다. 파일 잘 올라온 것 확인했습니다.) 감사합니다.
터미널에서 9003 포트 실행할 때, 9001 포트가 중복된다고 발생하는 경우는 명령어가 잘못되서 그렇습니다. 강의랑 조금 다르네요 ' ' 해당 부분을 확인해주세요. mvn spring-boot:run '- Dspring-boot.run .jvmArguments=-Dserver.port=9003'
안녕하세요. 현재 k8s 환경에서 롤링 업데이트를 통해 팟을 배포하는 방식을 채택하여 사용중에 있습니다. 메시지 컨슈밍 퍼포먼스를 줄여주기 위해 리밸런싱 시간을 줄여주는게 굉장히 중요하다는 생각이 드는데요. 강의를 보다보니 Static membership과 Cooperative sticky 2가지 방식이 이에 적합한 것 같아 보입니다. 실제 프로덕션 레벨에서는 어떠한 방식을 사용하는지 궁금합니다!
2가지 궁금한게 있는데요 첫번째는 카프카 커넥트와 직접 코드로 구현되는 컨슈머 중 하나를 선택해야 할 때 어떤 기준으로 선택하는 것이 좋을까요? 커넥트 장점을 보면 추측은 가능하지만 경험이 없으니 실무에서 어떨 때는 커넥트, 어떨 때는 컨슈머 직접 구현을 선택할 수 있는지(이건 경험 꽤 많아요) 기준이 궁금합니다 두번재는 자동으로 토픽 생성시에 시스템 종료하면 어떤게 문제가 될까요? 그레이스 풀 셧다운 관련인지 어떤 문제가 생기는지 궁금합니다 감사합니다.
안녕하세요 자주 질문을 드리게 되어 죄송합니다. 데이터가 이동하면서 아래와 같은 작업이 이루어지는 것을 강의를 통해 이해했습니다. source connector --> kafka : 직렬화 kafka --> sink connector : 역직렬화 그렇다면 혹시 java 를 사용하여 kafka로 바로 데이터를 적재 할 경우 sink connector로 데이터를 보낼 수가 있을까요?? 역직렬화 작업이 안될 것으로 보여서 가능한지 질문 드립니다. 가능하지 않다면 java로 kafka를 보낼 때 직렬화 작업이 된 상태로 보내야 할까요??
K8S나 Docker Swarm 없이 2대 이상의 Host PC에 Multi Cluster를 구성할 수 있을까요? 혹시 2대의 PC에 각각 Docker를 설치하고, 여기에 분산되서 올라간 Container들을 하나의 Network으로 묶는것이 가능한가 해서요. 방법이 있으면 알고 싶습니다

안녕하세요! 제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로 catalog-service 에서 example-catalog-topic 를 받은 뒤 상품의 개수를 파악 후 재고 유무의 따라 order-service 에 주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서 example-order-topic 에서 전달 받은 주문 상태를 업데이트 하는 로직을 구현하려고 했습니다. 로컬에서 order-service 와 catalog-service 의 consumer groupId 를 consumerGroupId 로 통일해서 사용 했을 때는 괜찮았으나, docker 에 올리니 example-order-topic 이 생성은 됐으나 구독 및 전달이 되지 않더라구요.... 혹시나 해서 order-service 의 consumer groupId 를 consumerGroupId2 로 변경하여 docker 에 올리니 정상 작동이 됩니다. 혹시 각각의 service 는 groupId 를 다르게 해주어야 할까요??
안녕하세요, 빅디님 ! 좋은강의 감사합니다. 가상서버 설치 + 설정에서 문제가 있어 질문남깁니다. macOS에서 M1칩을 탑재한 모델을 사용중인데, 최신버전의 virtualbox만 설치가 됩니다. (이하 버전은 설치조차 되지 않습니다..ㅠ) 설치는 되었으나 청천벽력같이.... 최신버전의 버츄얼박스에서는 server01/02가 시작이 되질 않습니다. 네트워크 구성 에러로 보입니다. [에러 전문] === Host-only adapters are no longer supported! For your convenience a host-only network named 'Legacy Network' has been created with network mask '255.255.255.0' and IP address range '192.168.56.1' - '192.168.56.254'. === 이러한 경우에 유일한 해결방법은 최신버전의 VM을 설치하고 네트워크 구성을 하지 않아야 시작이 되는 것으로 파악했습니다. 서버에 네트워크가 없다면 의미가 없어보입니다.. 이 수업에서는 네트워크 구성이 필수일까요? 혹은 다른 방법(가상화 서버 등) 아신다면 말씀 부탁드리겠습니다!! 감사합니다.
spring config를 적용하면 설정 값들에 암호화를 수행하여 "{cipher}..." 구문으로 적용할 수 있는데, bootstrap.yml 파일의 "encrypt.key-store.password", "encrypt.key-store.secret" 항목의 값은 암호화를 어떻게 할 수 있는지 방법 부탁드립니다.
안녕하세요 카프카 스트림즈 학습중에 궁금한 점이 있어 질문드립니다. 예를 들어 말씀드리겠습니다 kstream 으로 변경되는 상품의 가격 정보를 받아온다고 가정하고, ktable 로 해당 상품의 마스터성 정보를 받는다고 해보겠습니다. 카프카 스트림즈를 써도 결국엔 카프카 브로커에 로그로 쌓이는 것이고, 로그 압축이나 삭제 정책에 따라 A라는 상품의 정보가 있다가 사라질 수 있을 것 같은데요 4월 1일에는 A상품의 정보(상품이름, 판매처 등)가 로그에 있어서 데이터를 읽어올수 있었지만 4월4일에는 기간이 지나 삭제되었다거나 하는 경우가 있을 것 같아서요 카프카 스트림즈를 띄우는 서버의 메모리나 로컬 디스크에 모든 내용을 가지고 있는 건지가 궁금하구요 만약 해당 서버에 데이터가 있다면 서버가 다운되거나 했을때 리밸런싱 혹은 서버가 재시작 되었을때 사라진 로컬데이터의 복구 기능이 구현되어있는 건지 궁금합니다 또한 로컬에 저장된다면 그동안 스트림을 거쳐간 모든 데이터를 가지고 있는건지.. 데이터가 대용량이 된다면 로컬 머신의 저장공간을 고려해야하는지 궁금합니다 그리고.. 만약 카프카 스트림엔 데이터가 없고 rdb등의 저장소에 데이터가 있다면 이걸 가져와서 쓸수 있는지도 궁금합니다
안녕하세요. 강의 잘 수강중입니다. 다름 아니라, kafka에서 elastic search로 저장하는 일을 조만간 할 예정입니다. 본 과정을 다 수강하고 나면 그런 응용력이 생길지요? 아니면 connect 편 까지 다 수강해야 elastic search에 저장하는 응용력을 키울 수 있을지 문의드립니다. 감사합니다.
안녕하세요~선생님, 강의를 잘 해 주셔서 현재 RStudio를 진행하고 있는데 클라우라가 작동 되지 않습니다. 강의 후반에 오면서 메모리 문제가 발생했는데 어떻게 조치해야 합니까? 이전에 질문 조회를 해서 불필요한 파일 삭제하고, hadoop fs -setrep 1 /명령도 실행해 보았습니다. 클라우데라 현상태는 아래와 같습니다,, 제 PC사양은 RAM 32GB이고 아래와 같습니다
