클러스터 재실행하기

Hadoop Eco 사용 시 인스턴스를 재실행하거나 오류가 발생하여 클러스터를 재실행해야 할 경우, 클러스터를 재실행하는 방법은 다음과 같습니다.

  • 추천 실행 순서: Zookeeper → HDFS → YARN → Hive → HBase → History Server → Trino → Kafka → Druid → Redis → Superset → Hue, Zepplin 등

클러스터별 실행 순서는 다음과 같습니다.

  • HA: journalnode > namenode > zkfc > datanode
  • Single: namenode > secondary namenode > datanode

재부팅이나 오류가 발생하여 컴포넌트가 중지되는 경우 자동으로 3분마다 재시작합니다.
재시작을 원하지 않는 경우 컴포넌트를 명시적으로 종료(stop)하고, 서비스를 disabled 상태로 변경하여야 합니다.

Zookeeper 서비스 종료
sudo systemctl stop zookeeper.service
sudo systemctl disable zookeeper.service
