아래와 같은 내용의 오류가 발생하면서 zookeeper 데몬이 실행되지 않는 경우가 있는데 이는 마지막 transaction log파일에 문제가 발생하여 읽지 못해서 발생하는 오류임.
먼저 dataDir(예, /var/lib/zookeeper)로 지정된 위치의 version-2폴더로 이동한다.
마지막의 log파일과 snapshot파일을 지우고 파일 크기가 0인 log파일도 삭제하고 zookeeper를 재기동하면 정상적으로 데몬이 기동되며 현재의 log및 snapshot를 새롭게 생성한것을 확인할 수 있다.
----- 수행 명령문 예시
gooper@gsda1:/var/lib/zookeeper/version-2$ sudo rm log.19000a12e6 snapshot.19000a12e5
gooper@gsda1:/var/lib/zookeeper/version-2$ sudo rm log.19000a2c4e
