  - Upgrading Sentry
    Complete the following steps to upgrade manually. If you installed Sentry with the MapR Installer, use the latest version of the MapR Installer to perform the upgrade.
  - Configuring Sentry
    The steps to configure Sentry are determined by the storage model, the type of security used by the cluster, and the components that will use Sentry authorization.
    - Configure Sentry to use Database Storage
      As of Sentry 1.6, the database storage model is the preferred method for storing privileges and roles. When you configure Sentry to use the database storage model, it also includes a service that is managed by Warden.
    - Configure Sentry to use File-Based Storage
      You can configure Sentry to use the file-based storage model where permissions are stored in the global-policy.ini file.
    - Configure Sentry to use Kerberos Authentication
      You can configure Sentry to run in a secure cluster that uses Kerberos authentication.
  - Integrating Sentry
    Integrate Sentry with other ecosystem components to enable those components to use Sentry authorization. You can also integrate Sentry with Hue in order to use the Hue Security application to manage Sentry privileges and roles.

Configuring Sentry

The steps to configure Sentry are determined by the storage model, the type of security used by the cluster, and the components that will use Sentry authorization.

Configure Sentry to use one of the following storage models: file-based storage or database storage.
If the cluster is secure, you can configure Sentry to use kerberos authentication.
Based on your requirements, complete the steps to integrate Sentry with one or more ecosystem components.
