    +Configuration files for the HAWQ Ranger Plug-in Service are located in the `$GPHOME/ranger/etc`
directory. These files include:
    +
    +| File     |  Description     |
    +|-------------|---------------------------|
    +| ranger-hawq-audit.xml |  HAWQ Ranger audit-related configuration, including the audit
provider (log4j, Solr, HDFS) and provider-specific configuration |
    +| ranger-hawq-security.xml |  HAWQ Ranger service configuration, including the policy
change polling interval |
    +| rps.properties |  HAWQ Ranger deployment-related configuration, including the RPS port
definition and JVM parameters|
    +
    +You should not need to modify RPS configuration in a default installation.  Any configuration
changes you do make after you have registered the HAWQ Ranger Plug-in requires a restart of
the service. You can either restart the HAWQ cluster or restart just the HAWQ Ranger Plug-in
Service:

    +``` shell

    +The default polling interval for HAWQ RPS policy updates is 30 seconds. To increase or
decrease this value, update the `ranger.plugin.hawq.policy.pollIntervalMs` property setting
in the `ranger-hawq-security.xml` file:
