| <p>This document describes how to configure Ozone HTTP web-consoles to require user authentication.</p> |
| <h3 id="default-authentication">Default authentication</h3> |
| <p>By default Ozone HTTP web-consoles (OM, SCM, S3G, Recon, Datanode) |
| allow access without authentication based on the following default configurations.</p> |
| <table> |
| <thead> |
| <tr> |
| <th>Property</th> |
| <th>Value</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr> |
| <td>ozone.security.http.kerberos.enabled</td> |
| <td>false</td> |
| </tr> |
| <tr> |
| <td>ozone.http.filter.initializers</td> |
| <td><empty></td> |
| </tr> |
| </tbody> |
| </table> |
| <p>If you have an SPNEGO enabled Ozone cluster and want to disable it for all Ozone services, |
| just make sure the two key mentioned are configured as above.</p> |
| <h3 id="kerberos-based-spnego-authentication">Kerberos based SPNEGO authentication</h3> |
| <p>However, they can be configured to require Kerberos authentication using HTTP SPNEGO protocol (supported |
| by browsers like Firefox and Chrome). To achieve that, the following keys must |
| be configured first.</p> |
| <table> |
| <thead> |
| <tr> |
| <th>Property</th> |
| <th>Value</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr> |
| <td>hadoop.security.authentication</td> |
| <td>kerberos</td> |
| </tr> |
| <tr> |
| <td>ozone.security.http.kerberos.enabled</td> |
| <td>true</td> |
| </tr> |
| <tr> |
| <td>ozone.http.filter.initializers</td> |
| <td>org.apache.hadoop.security.AuthenticationFilterInitializer</td> |
| </tr> |
| </tbody> |
| </table> |
| <p>After that, individual component needs to configure properly to completely enable |
| SPNEGO or SIMPLE authentication.</p> |
| <h3 id="enable-spnego-authentication-for-om-http">Enable SPNEGO authentication for OM HTTP</h3> |

| <td>/path/to/HTTP.keytab</td> |
| </tr> |
| </tbody> |
| </table> |
| <p>Note: Ozone datanode does not have a default webpage, which prevents you from |
| accessing “/” or “/index.html”. But it does provide standard |
| servlet like jmx/conf/jstack via HTTP.</p> |
| <p>In addition, Ozone HTTP web-console support the equivalent of Hadoop’s Pseudo/Simple authentication. |
| If this option is enabled, the user name must be specified in the first browser interaction using the user.name |
| query string parameter. e.g., http://scm:9876/?user.name=scmadmin.</p> |
