cloudera 설치가 안 되는 문제점 때문에 알게 된 yum 버그

http://impactcore.blogspot.kr/2011/03/can-not-remove-package-with-yum.html

발단; cloudera package 설치 중 cloudera-scm-agent가 설치가 제대로 되지 않아 결국 cloudera-manager 설치 중 오류 발생

메시지에는 /etc/cloudera-scm-agent/config.ini가 존재하지 않는다고 나옴

원인; cloudera package를 여러 번 설치 삭제 하던 중 yum 설정 부분에 문제가 생긴 걸로 추정

수십번 재설치를 했으나 진행이 되지 않던 중, cloudera-manager-agent나 cloudera-manager-daemons가 제대로 제거되지 않았다는 점을 알게 됨

이 문제는 yum의 bug인데, 다음과 같이 삭제를 할 수 있다

# rpm -e --noscripts cloudera-manager-agent cloudera-manager-daemons

yum에서 설치 가능한 cloudera package를 검색할 때 다음과 같이 나오면 정상(cloudera-manager-agent나 cloudera-manager-daemons가 제대로 삭제되지 않으면 여기 나오지 않음)
