Restart the Ranger Services

Once you have re-installed each Ranger component, you will then need to restart these components to ensure the new configurations are loaded in your cluster. This includes restarting the Policy Admin and UserSync components, NameNode, and each Ranger plugin.


Before restarting the NameNode, make sure to remove the set-hdfs-plugin-env.sh from /etc/hadoop/conf. You will need to re-enable the NameNode after finishing the upgrade.

The Non-Ambari Cluster Installation Guide describes how you can start the following Ranger services:

  • Ranger Policy Admin service

    service ranger-admin start
  • Ranger UserSync service

    service ranger-usersync start
