JAVA openjdk-11.0.2_linux-x64

정상작동 테스트

docker exec -it namenode /bin/bash start-all.sh

hadoop fs -put /opt/hadoop/LICENSE.txt /tmp/test/wordcount/

hadoop jar /opt/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.3.6.jar wordcount /tmp/test/wordcount /tmp/test/wordcount_out

hdfs fsck /tmp/test/wordcount_out -files -blocks -locations

기존프로젝트와의 차이점

  • 프로젝트 간소화
    • 하둡 시스템 구조 변경
      • Resocure Manager가 네임노드와 같이 실행
      • zookeeper, spark shell ... 제거됨
      • MapReduce까지
  • 하둡 버전 변경
  • ssh 사용
    • start-dfs.sh 사용 가능
