맵 축소 프로그램이 CSV 파일을로드 할 수 없습니다 hbase 테이블

Question

map-reduce 프로그램을 사용하여 CSV 파일을로드하려면이 명령을 실행하고 있습니다. 성공적으로 실행 중이지만 hbase 테이블을 검색 할 때 0 행이 표시됩니다. 다음
은 실행 과정의 콘솔 로그 데이터입니다 :

내가 HBase를 테이블에 값을 삽입하고있는 클래스이며, 은 '부피', '필드'를 생성 명령을 사용하는 간단한 테이블을 생성한다. 데이터 출력을 검색하는 중 표시되지 않습니다.

이 프로그램은 의사 배포 모드에서 성공적으로 실행됩니다.

시도의 HADOOP_CLASSPATH = 'HBase를 클래스 경로'하둡 항아리 데스크탑/bulk.jar/사용자/하둡/사용자/하둡/부하 대량

나는 MR 정확한 입력 경로 파일 이름을 사용하는 경우 확실하지 않다. 경로 (폴더 경로)를 예상합니다.
