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.

  1. Go to the HDFS service.
  2. Select Actions > Disable High Availability.
  3. Select the hosts for the NameNode and the Secondary NameNode and click Continue.
  4. Select the HDFS checkpoint directory and click Continue.
  5. Confirm that you want to take this action.
  6. Configure the Hive Metastore to use HDFS HA.
