HDFS 벤치마킹 하기

윤's군 2013. 10. 21. 17:23

hadoop-test-*.jar 파일을 이용하여 테스트를 하게 된다


쓰기 테스트

$bin/hadoop jar hadoop-test-1.2.1.jar TestDFSIO -write -nrFiles 5 -fileSize 100


-write 옵션은 쓰기 성능을 벤치마킹한다.

-nrFiles 옵션은 몇개의 파일을 생성할 것인가 하는 옵션이다.

-fileSize 옵션은 메가 바이트 단위로(MBytes)로 파일을 생성하겠다냐는 옵션이다.



우분투 13.04, 자바 1.7.40 hadoop 1.2.1버전, 가상분산환경에서 테스트 하였다.


 bin/hadoop jar hadoop-test-1.2.1.jar TestDFSIO -write -nrFiles 5 -fileSize 100
