Disabling and redeploying HDFS HA
When you disable HDFS HA, Cloudera Manager ensures that one NameNode is active, and saves the namespace. Then it stops the standby NameNode, creates a Secondary NameNode, removes the standby NameNode role, and restarts all the HDFS services.
- Go to the HDFS service.
- Select .
- Select the hosts for the NameNode and the Secondary NameNode and click Continue.
- Select the HDFS checkpoint directory and click Continue.
- Confirm that you want to take this action.
- Configure the Hive Metastore to use HDFS HA.
