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.

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?
