이 오류가 발생합니다. 많은 사람들 이이 오류가 발생한다는 것을 읽었지만 이에 대한 해결책을 찾지 못했습니다. 누구든지 도울 수 있습니까 ??

해결법

1. ==============================

   1.별도의 사용자 만들기-hduser, 항상 권장

   별도의 사용자 만들기-hduser, 항상 권장

   - do chown -R 755 /usr/local/hadoop
   - when creating tmp paths like /app/hadoop/tmp, apply the same settings as above
   

   바라건대, 이것은 문제를 해결할 것입니다.

   이 문제는 hadoop이 아닌 권한과 관련이 있습니다.

2. ==============================

   2.다음은 매우 유용한 제안입니다.

   다음은 매우 유용한 제안입니다.
