Restart cluster
Restart cluster
When using Hadoop Eco, if you need to restart an instance or if an error occurs requiring a cluster restart, follow these steps:
- Recommended restart order: Zookeeper → HDFS → YARN → Hive → HBase → History Server → Trino → Kafka → Druid → Redis → Superset → Hue, Zeppelin, etc.
The restart order for each cluster is as follows:
- HDFS
- YARN
- Hive
- HBase
- Dataflow
- HA: journalnode > namenode > zkfc > datanode
- Single: namenode > secondary namenode > datanode
- HA, Single: resource manager > node manager
- HA, Single: metastore > hiveserver2
- HA, Single: HMaster > regionserver
- HA, Single: kafka > druid > redis > superset
tip
If a reboot or error causes a component to stop, it will automatically restart every 3 minutes.
If you do not want it to restart, you must explicitly stop the component and set the service to disabled.
Stop Zookeeper service
sudo systemctl stop zookeeper.service
sudo systemctl disable zookeeper.service
