cloudera CDH 5.8.0을 사용하여 하나의 마스터 노드와 세 개의 슬레이브로 클러스터를 만들었습니다. 몇 가지 설정 작업을 마친 후에 나는 모든 서비스를 건강하게 만들었지 만 한 가지 : HBase. 다시 시작한 후 몇 분 후에 건강이 안 좋게됩니다.HBase 서비스에서 Service Monitor가 활성 마스터를 찾지 못했습니다.
Cloudera Manager에서 표시되는 오류 : "불량 : 마스터 요약 : 서비스 모니터가 활성 마스터를 찾지 못해이 상태 테스트가 잘못되었습니다." 서비스 모니터 로그를 확인한 결과 다음과 같은 경고가 나타났습니다.

이 문제를 해결하는 알려진 방법이 있습니까? 마스터 노드를 HBase Master로, 슬레이브를 HBase RegionServers로 설정했습니다.
