Yarn 응용 프로그램이 이미 종료되었습니다! 종료되었거나 응용 프로그램 마스터를 시작할 수 없습니다.

오늘 밤 yarn에서 spark의 클라이언트 모드를 실행할 때 불편함을 주는 오류가 발생했습니다. 인터넷에서 해결책을 찾았지만 문제의 구체적인 원인이 명확하지 않습니다. 아시는 분이 조언을 해주실 수 있기를 바랍니다. 나는 매우 감사하게 될 것입니다! ! !
오류는 다음과 같습니다.

Warning: Master yarn-client is deprecated since 2.0. Please use master "yarn" with specified deploy mode instead.

그 이유는 java8을 사용하기 때문에 yarn-site.xml에서 설정한 것 같습니다.

    yarn.nodemanager.pmem-check-enabled
    false



    yarn.nodemanager.vmem-check-enabled
    false
