무료판 고르고서 계속 누르면 저렇게 빈 창으로 로딩만 계속 되는데 해결 방법이 없을까요? 여러번 새로고침해도 똑같이 됩니다.

강의에서 버추어박스는 다른 것과 달리 올드버전을 해야 문제 없다고 하여 영상 그대로 5.0버전 설치했는데너무 예전 버전이라 그런지 아예 윈도우에서 실행이 안되게 되어있습니다. 이러면 아예 최신 버전으로 설치해도 무방한가요? 

주제 1,2에선 문제 없이 됐었는데 주제 3에서 예약을 실행하니 테이블은 생성 되는데 그 이후 데이터 삽입이 안됩니다. chat gpt 통해 여러가지 시도 해봤는데 해결이 안되네요. 어떻게 해결 가능할까요?하이브 쿼리는 강사님 쿼리 복붙 했습니다.jar 파일 돌렸을 때 날짜는 20250625였고 강의 내용대로 20200322을 다 넣었었습니다. 워크플로우 매개변수 설정도 즉시실행으로 20200322 값을 넣었습니다.JOB - 예약 - LOG2025-07-01 08:19:11,671 INFO org.apache.oozie.command.coord.CoordActionInputCheckXCommand: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[0000141-250701040825040-oozie-oozi-C@131] [0000141-250701040825040-oozie-oozi-C@131]::CoordActionInputCheck:: Missing deps: 2025-07-01 08:19:11,673 WARN org.apache.oozie.util.DateUtils: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[0000141-250701040825040-oozie-oozi-C@131] GMT, UTC or Region/City Timezone formats are preferred instead of Asia/Seoul 2025-07-01 08:19:11,673 WARN org.apache.oozie.util.DateUtils: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[0000141-250701040825040-oozie-oozi-C@131] GMT, UTC or Region/City Timezone formats are preferred instead of Asia/Seoul 2025-07-01 08:19:11,678 INFO org.apache.oozie.command.coord.CoordActionReadyXCommand: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[] Not starting any additional actions because max concurrency [1] for coordinator [0000141-250701040825040-oozie-oozi-C] has been reached. 2025-07-01 08:19:11,790 INFO org.apache.oozie.command.coord.CoordActionInputCheckXCommand: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[0000141-250701040825040-oozie-oozi-C@132] [0000141-250701040825040-oozie-oozi-C@132]::CoordActionInputCheck:: Missing deps: 2025-07-01 08:19:11,792 WARN org.apache.oozie.util.DateUtils: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[0000141-250701040825040-oozie-oozi-C@132] GMT, UTC or Region/City Timezone formats are preferred instead of Asia/Seoul 2025-07-01 08:19:11,792 WARN org.apache.oozie.util.DateUtils: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[0000141-250701040825040-oozie-oozi-C@132] GMT, UTC or Region/City Timezone formats are preferred instead of Asia/Seoul 2025-07-01 08:19:11,796 INFO org.apache.oozie.command.coord.CoordActionReadyXCommand: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[] Not starting any additional actions because max concurrency [1] for coordinator [0000141-250701040825040-oozie-oozi-C] has been reached. 2025-07-01 08:19:18,058 INFO org.apache.oozie.command.coord.CoordActionReadyXCommand: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[] Not starting any additional actions because max concurrency [1] for coordinator [0000141-250701040825040-oozie-oozi-C] has been reached. 2025-07-01 08:19:30,847 INFO org.apache.oozie.service.StatusTransitService$StatusTransitRunnable: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[-] Running bundle status service from last instance time = 2025-06-30T23:18Z 2025-07-01 08:19:30,848 INFO org.apache.oozie.service.StatusTransitService$StatusTransitRunnable: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[-] Released lock for [org.apache.oozie.service.StatusTransitService] 2025-07-01 08:20:18,064 INFO org.apache.oozie.command.coord.CoordActionReadyXCommand: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - 예약] JOB[0000141-250701040825040-oozie-oozi-C] ACTION[] Not starting any additional actions because max concurrency [1] for coordinator [0000141-250701040825040-oozie-oozi-C] has been reached.JOB - 워크플로우 - LOG2025-07-01 08:12:00,094 INFO org.apache.oozie.action.hadoop.Hive2ActionExecutor: SERVER[server02.hadoop.com] USER[admin] GROUP[-] TOKEN[] APP[Subject 3 - Workflow] JOB[0000143-250701040825040-oozie-oozi-W] ACTION[0000143-250701040825040-oozie-oozi-W@hive-6885] Starting action.

java와 이클립스 대신 인텔리제이25버전과와 자바21버전 설치해도 되나요?오라클에서 뒤져봤는데 17버전을 도저히 못찾겠어서요. 혹시 17버전 링크라도 알려주실 수 있나요? 그리고 벌쳐박스도 7..1로 설치해도 되나요? 혹시 구버전도 링크 알려주실수있나요?

버츄얼박스 5.0버전은 다운로드 링크 눌러도 다운로드가 안됩니다.. 다른버젼은 잘 다운되는데 5.1로 해도되나요?

안녕하세요, 강사님. 강의대로 진행했음에도 불구하고 계속 사진처럼 빨갛게 뜹니다. 제가 처음에 클라우데라 매니저 설치할 때 실수를 반복하여 클러스터를 세 번 정도 설치했다가 삭제하고 마지막으로 한 번 더 제대로 설치했는데, 이전에 설치했던 parcel 혹은 다른 잔여 파일이 남아서 그런 걸까요? parcel을 설치할 때마다 c 디스크 공간이 줄어들었던 걸 보면 잔여 파일이 남은 것 같긴 한데 어떻게 삭제해야 할까요?

파일만 가지고 가서 다른곳에서 실행하고 싶은데 ISO 이미지 포함이 안되도 되나요?? 위 설정대로 하면 가져오기만 해도 실행이 될까요? 초반에 .vbox 머신추가했던것 처럼 하고 싶습니다. 수업 듣는 내내 궁금했는데 저기가 원천으로 사용하는 5개 테이블의 create 문을 알고싶습니다. 어떤 컬럼이 있고 각 컬럼들은 무엇을 의미하는지는 강의나 교안에 잘 안나와 있어서 한눈에 안들어 올때가 있었습니다. 테이블정의서를 그려서 좀 보고 싶습니다.

모니터링을 하고 싶은데 위 에러가 뜨더니 이후엔 Magnagement를 켜면 나머지 기능들에 에러가 나서 작동이 아예 안되는 수준입니다.

 ascii 관련 에러가 났는데 어느 부분에서 고쳐야하는지 모르겠어요
