The Ranger plug-in service implements the Ranger REST API to bridge all requests between the Ranger Policy Manager and a HAWQ instance. -HAWQ also provides a JAR library that enables the Ranger Policy Manager to lookup HAWQ metadata (the names of databases, schemas, tables, and so forth) to populate the user interface and assist in creating new policies. This JAR uses a JDBC connection to HAWQ, and requires a one-time registration with the Ranger Policy Manager. +HAWQ also provides a JAR library that enables the Ranger Policy Manager to lookup HAWQ metadata (the names of databases, schemas, tables, and so forth) to populate the user interface and assist in creating new policies. This JAR uses a JDBC connection to HAWQ, and requires a one-time registration with the Ranger Policy Manager. See [Configuring HAWQ to use Ranger Policy Management](ranger-integration-config.html). -A single configuration parameter, `hawq_acl_type` determines whether HAWQ defers all policy management to Ranger via the plug-in service, or whether HAWQ handles authorization natively using catalog tables. By default, HAWQ uses SQL commands to create all access policies, and the policy information is stored in catalog tables. When you enable Ranger integration for policy management, any authorization policies that you have configured in HAWQ using SQL no longer apply to your installation; you must create new policies using the Ranger interface.

You can use the configuration parameter `that` to control how frequently the plug-in service contacts the Ranger Policy Manager to refresh cached policies.
