하둡 예를 실행할 때, 나는 ".staging / job_1541144755485_0002 / job.splitmetainfo 존재하지 않는다"는, 내가 무엇을 할 수 발생?

내 구성은 다음과 같습니다 : 나는 pc720 (10.10.1.1)과 pc719 (10.10.1.2) 각각 하둡 실험이 기계를 사용했다. JDK (버전 1.8.0_181)는 apt-get을 설치됩니다. Hadoop2.7.1는 https://archive.apache.org/dist/hadoop/common/hadoop-2.7.1/에서 다운로드 할 수 있습니다 및 / opt를 넣어 /

1 단계: 나는 추가하는 /etc/bash.bashrc 구성

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64  
export PATH=${JAVA_HOME}/bin:${PATH}  
export HADOOP_HOME=/opt/hadoop-2.7.1  
export PATH=${HADOOP_HOME}/bin:${PATH}  
export PATH=${HADOOP_HOME}/sbin:${PATH}

다음 "소스의 / etc / 프로필"실행

2 단계: 나는 XML을 구성합니다

3 단계 : 에서 / 루트 / 여러 디렉토리를 설립 :

mkdir hadoop_store
mkdir hadoop_store/hdfs
mkdir hadoop_store/tmp
mkdir hadoop_store/hdfs/datanode
mkdir hadoop_store/hdfs/namenode

그럼, /opt/Hadoop-2.7.1/bin로 바뀌 실행

./hdfs namenode –format
cd ..
cd sbin/
./start-all.sh
./mr-jobhistory-daemon.sh start historyserver

실행 JPS, pc720 쇼 후

pc719 쇼

여기에 도달, 내 hadoop2.7.1가 성공적으로 설치 및 구성되었습니다 생각합니다. 그러나 문제가되었다.

나는 /opt/hadoop-2.7.1/share/hadoop/mapreduce/하는 쇼있는 걸까요?

그럼 난 하둡 항아리 하둡 - 맵리 듀스 - 예-2.7.1.jar 파이 2를 실행

나는 많은 솔루션을 시도했지만 쓸모없는 듯했다. 이 문제는 약 1 주일 동안 저를 혼동하고있다. 내 구성에서 실수가 있습니까? 내가 무엇을 할 수 있을지? 제발 도와주세요. 감사!

해결법

==============================
1.나는 당신이 놓친 믿고 / A 최종 offs.defaultFS 값이 될 것이다 <값> HDFS : //10.10.1.1 : 9000 /

나는 당신이 놓친 믿고 / A 최종 offs.defaultFS 값이 될 것이다 <값> HDFS : //10.10.1.1 : 9000 /

일반적 HDFS 유지된다 yarn.app.mapreduce.am.staging-DIR 의해 구성되는 것을 유의 /tmp/hadoop-yarn/staging/root/.staging/job_1541144755485_0002/job.splitmetainfo. 이것은 우리에게 HDFS의 문제가 힌트를 제공합니다.
