| <p>Apache Ranger™ is a framework to enable, monitor and manage comprehensive data |
| security across the Hadoop platform. Apache Ranger has supported Ozone authentication |
| since version 2.0. However, due to some bugs in 2.0, Apache Ranger |
| 2.1 and later versions are recommended.</p> |
| <p>To use Apache Ranger, you must have Apache Ranger installed in your Hadoop |
| Cluster. For installation instructions of Apache Ranger, Please take a look |
| at the <a href="https://ranger.apache.org/index.html">Apache Ranger website</a>.</p> |
| <p>If you have a working Apache Ranger installation that is aware of Ozone, then |
| configuring Ozone to work with Apache Ranger is trivial. You have to enable |
| the ACLs support and set the acl authorizer class inside Ozone to be Ranger |
| authorizer. Please add the following properties to the ozone-site.xml.</p> |
| <table> |
| <thead> |
| <tr> |
| <th>Property</th> |
| <th>Value</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr> |
| <td>ozone.acl.enabled</td> |
| <td>true</td> |

| <td>ozone.acl.authorizer.class</td> |
| <td>org.apache.ranger.authorization.ozone.authorizer.RangerOzoneAuthorizer</td> |
| </tr> |
| </tbody> |
