cdh에서 zookeeper를 어떻게 관리하고 zk상태를 보는 명령 요약

참고 데이터 디렉토리가 초기화되지 않으면 ZooKeeper 서버를 시작할 수 없습니다.//운영 환경에서는 ZooKeeper를 여러 개의 서버가 있는 컬렉션으로 배치해야 합니다.ZooKeeper 서비스는 컬렉션에 있는 대부분의 서버만 사용할 수 있습니다.최소 집합 크기는 세 개의 ZooKeeper 서버이며, Cloudera는 각 서버가 단독 컴퓨터에서 실행되는 것을 권장합니다.또한 가능하다면 ZooKeeper 서버 프로세스에 전용 디스크 저장소가 있어야 합니다.
