+The HAWQ Ranger Plug-in Service (RPS) log files may be useful in helping
diagnose Ranger connectivity and authorization problems when Ranger
authorization is enabled for HAWQ. You will find these log files in the
`$GPHOME/ranger/plugin-service/logs/` directory. In addition to RPS
service-related logs, this directory includes the `log4j` provider `audit.log`
file. (Refer to [Auditing Authorization Events](../ranger/ranger-auditing.html)
for information on configuring HAWQ Ranger audit logging.)
