    +
    +Before you configure HAWQ Ranger authentication in high availability mode, ensure that you have:
    +
    +- Installed or upgraded to a version of HAWQ that includes support for HAWQ Ranger Authentication.
    +
    +- Configured Ranger Admin for high availability.
    +
    +- Configured a HAWQ standby master node for your HAWQ cluster.
    +
    +    You must configure a standby master for your HAWQ deployment before enabling HAWQ Ranger high availability mode. If you have not configured your HAWQ standby master, follow the instructions in [Adding a HAWQ Standby Master](../admin/ambari-admin.html#amb-add-standby) (if you manage your HAWQ cluster with Ambari) or [Configuring Master Mirroring](../admin/MasterMirroring.html#standby_master_configure) (for a command-line-managed HAWQ cluster).

    +    The HAWQ Ranger Plug-in Service runs on the HAWQ master node. If you have not yet enabled the Ranger Plug-in Service, refer to [Install Ranger Connectivity to HAWQ](ranger-integration-config.html#jar) for registration instructions. Make sure to identify the Ranger Admin HA proxy when you enable the plug-in.
