[HADOOP] 이 / tmp를 / 아래 디렉토리를 만들 수 없습니다로 충돌 원사 타임 라인 서비스

이 / tmp를 / 아래 디렉토리를 만들 수 없습니다로 충돌 원사 타임 라인 서비스

아파치 TimelineServer 문서에서 고급 구성으로 하둡의 역사 (타임 라인) 서비스를 설정하기 위해 노력하고있어. 나는 다음과 같은 명령을 사용하여 서비스를 시작합니다 : $은 historyserver 시작 yarn-daemon.sh. 그럼 난 ApplicationHistoryServer을 설치하고 실행 볼 수 있지만 잠시 후에는 (원사 arbi-historyserver-annaba.log에서) 다음과 같은 예외와 충돌 :

그것은 yarn.timeline-service.generic - 응용 프로그램 history.fs - 역사 - store.uri의 기본값입니다 direcotry / tmp를 / 하둡 - arbi / 실 / 타임 라인 / 일반 - 역사 / ApplicationHistoryDataRoot를 작성하는 데 실패 것 같은데 속성. 다른 하둡이 성공적으로 / tmp를 / 아래 만물을 창조 IT 서비스를하는 동안이 서비스가 실패하지만 왜 궁금해 :

또한이 이름 노드의 안전 모드는 무엇인가?
