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  

안녕하세요.빅디님의 책과 강의로 열심히 따라가고 있는데 여러 업무를 병행하다보니 강의의 반도 진행하지 못했습니다. 강의를 들으면 정말 제가 알지 못했던 분야를 너무 쉽게 알아가는 기쁨에 가슴이 뛰는데 업무에 치이면서 살다보니 어느덧 강의 만료일이 다가 왔습니다.혹시 기간 연장을 조금 더 해주실수 있다면 부탁드리겠습니다.이 강의는 꼭 완료하고 싶습니다.부탁드리겠습니다. 감사합니다.

안녕하세요 지금까지 강의 잘 따라오고 있었는데요 spark ssh 접속하여 shell 실행 후 smartcar_master_df 생성까지 잘 되었는데 smartcar_master_df 조회를 하면 아래와 같은 오류가 발생합니다. 구글링해서 찾아봐도 해결이 안되는데 도움 부탁드립니다. >> 오류메세지 >> WARN cluster.YarnScheduler: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources

안녕하세요. 업무를 병행하면서 학습을 하기 쉽지가 않네요... 혹시 연장 신청이 가능할지 궁금해서 문의 남깁니다. 가능하다면 꼭 좀 부탁드리겠습니다. 감사합니다.

주키퍼 설정을 data node인 서버 02로 선택하는 건가요? 말이 끊겨서 안들리네요.그리고 이유를 알고 싶습니다.

안녕하세요.강의를 들으며 jar 프로그램(자바 기반 프로그램)들이 플럼에 의존되는것을 확인할 수 있었는데,이것을 파이썬 코드로 바꿔서 conf를 변경해도 동작이 되는걸까요?   

가상머신을 돌리려는데 이런 오류가 뜹니다. "시스템에서 VT-x/AMD-V 하드웨어 가속을 사용할 수 없습니다. 64비트 게스트가 64비트 CPU를 인식할 수 없으며 부팅할 수 없을 것입니다." 혹시 해결하신분 계실까요?

안녕하세요, 15일간의 빅데이터 파일럿 프로젝트 강의 수강생입니다.유익한 강의 감사합니다. 설명을 잘해주셔서 큰 어려움 없이 듣고 있습니다.다만, VM 환경 구성 중 로그인 관련 문제가 생겨서 질문드립니다. Server01과 Server02에서 모두 로그인을 요청하고 있으며, 다음 단계로 진행할 수 없습니다.윈도우11 PC에서 Virtual Box 버전은 VirtualBox 6.1.40 입니다. 강의와 동일한 5 버전이 지원되지 않아서 가장 가까운 6.1.40 버전과 최신 7 버전으로 설치했습니다.C, D 드라이브 용량은 200GB 이상 여유공간이 있으며, SSD입니다. 아래는 과거 게시판 질문 답변과 구글링을 바탕으로 시도한 방법입니다.Virtual Box 삭제 및 설치 - 6, 7 버전 모두 시도 / Server01, Server02 파일 재다운로드-> Host-Only Ethernet Adapter를 찾지 못하는 경우가 있었으나, Virtual Box의 Host-Only Ethernet Adapter 재설정 후 접속해도 로그인창이 나왔습니다.Host-Only Ethernet Adapter 에러Failed to open/create the internal network 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter' (VERR_INTNET_FLT_IF_NOT_FOUND). Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND). 결과 코드: E_FAIL (0x80004005) 구성 요소: ConsoleWrap 인터페이스: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}-> 해당 에러는 새로운 Host-Only Ethernet Adapter를 추가하여 해결되었습니다.->Server02, 01 순서로 실행하고, 각각 하나씩 실행도 했습니다. 윈도우 제어판 Host-Only Ethernet Adapter 설정-> 윈도우 제어판 네트워크 설정에서 Host-Only Ethernet Adapter 사용 안함으로 설정하고, 재설치하였으나 로그인창 문제가 해결되지 않았습니다.현재 Virtual Box 네트워크 환경 설정입니다. 관련이 있는지는 모르겠지만, VBoxNetDHCP 프로세스 종료 후에도 진행하였으나 동일한 현상이 발생했습니다. 해당 문제를 해결할 방법 또는 추가로 시도할 방법이 있을까요?답변 기다리겠습니다. 감사합니다.   

JPA같은 경우에는 관계형 데이터베이스와 객체를 서로 매핑할수있게 하는 프레임워크인걸로 알고있습니다 그러면 이때 MySQL, Oracle 같은 데이터베이스가 있는데 이때 이 데이터베이스는 RDB 기반인데, 그러면 빅데이터를 위해 사용하는 Impala, Hive 같은 DB는 MPP DB도 JPA 프레임워크를 사용이 가능할까요? 

안녕하세요! 좋은 강의 잘 보고 있습니다~   제플린 파트에서 다음과 같은 오류를 만나게되었는데 혹시 제가 놓친 부분이 있을까요?? 오류 메세지만으로는 알기가 좀 어렵네요 ㅠ   작성 내용은 예제 소스에서 biz_date 부분만 바꾸었습니다.  

Mac으로 환경 구성 하려고 하는데 앞으로 수업 내용들이 전부 Window 기준으로 되어있다고 하셔서, mac 사용시 혹시 크게 불편한 부분이 있나요?

멀티 브로커(Broker1, Broker2)와 Multi Node를 가지는 아키텍처에 대해서 설명해주셨는데요. 중간에 각 Broker에 있는 Topic들을 하나도 묶을 수 있다는 내용이 있는데 정확히 어떤 의미인가요? Broker들끼리 서로 데이터를 공유한다는 말인가요? Consumer 1과 Consumer2가 같은 저장소를 바라본다는 말씀이 Node 1에 접근하더라도 Node 2에 있는 데이터에 접근 할 수 있다는 의미인가요?

vitualbox 최신 버전으로 설치하고 강의에 나와있는 부분을 따라서 실행하다가 클러스터 설치 중 다음과 같은 에러가 발생합니다. vitualbox 다른 버전으로 설치하면 아예 실행도 안됩니다. (강의자료 19페이지 수행 중 에러 발생)  

1. java 버전으로 1.8을 설치한다고 하셨는데 1.8로 설치하는 이유를 알고 싶습니다.  2. 환경 변수에 이미 JAVA_HOME이 있으면 어떻게 해야하나요? 3. 이클립스 installer를 다운받고 실행했더니 다음과 같이 뜨는데 어떤 것을 설치해야하나요 4. vitualbox download 하는 부분에서 no longer supported라고 명시되어있음에도 다운받아서 사용하는 이유를 알고 싶습니다. 5. 파일질라를 사용하는 대신에 scp 나 rsync 명령어를 사용하여 진행할 수 있을까요

아파치센트리의 경우 중앙에 서버를 두고 주변 노드들에게 접근 권한을 주는 것으로 이해를 했는데 커베로스는 클라이언트마다 서버를 따로따로 두는 것인가요? 커베로스도 KDC를 하나 두고 각 클라이언트들이 인증을 요청해서 티켓을 받는 방식인가요?   아, 아파치 센트리에서는 노드들에게 센트리 에이전트를 설치하는 대신 커베로스에서는 인증 요청하는 방식으로 진행되는 것인가요?
