| <p>Datanodes under Hadoop is traditionally secured by creating a Keytab file on |
| the datanodes. With Ozone, we have moved away to using datanode |
| certificates. That is, Kerberos on datanodes is not needed in case of a |
| secure Ozone cluster.</p> |
| <p>However, we support the legacy Kerberos based Authentication to make it easy |
| for the current set of users.The HDFS configuration keys are the following |
| that is setup in hdfs-site.xml.</p> |
| <table> |
| <thead> |
| <tr> |
| <th>Property</th> |
| <th>Description</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr> |
| <td>dfs.datanode.kerberos.principal</td> |
| <td>The datanode service principal. <br/> e.g. <a href="mailto:dn/_HOST@REALM.COM">dn/_HOST@REALM.COM</a></td> |
| </tr> |
| <tr> |
| <td>dfs.datanode.keytab.file</td> |
| <td>The keytab file used by datanode daemon to login as its service principal.</td> |
| </tr> |
| <tr> |
| <td>hdds.datanode.http.auth.kerberos.principal</td> |
| <td>Datanode http server service principal.</td> |
| </tr> |
| <tr> |
| <td>hdds.datanode.http.auth.kerberos.keytab</td> |
| <td>The keytab file used by datanode http server to login as its service principal.</td> |
| </tr> |
| </tbody> |
| </table> |
| <h2 id="how-a-datanode-becomes-secure">How a datanode becomes secure.</h2> |
| <p>Under Ozone, when a datanode boots up and discovers SCM’s address, the first |
| thing that datanode does is to create a private key and send a certificate |
| request to the SCM.</p> |
| <h3>Certificate Approval via Kerberos <span class="badge badge-secondary">Current Model</span></h3> |
| SCM has a built-in CA, and SCM has to approve this request. If the datanode |
| already has a Kerberos key tab, then SCM will trust Kerberos credentials and |
| issue a certificate automatically. |
| <h3>Manual Approval <span class="badge badge-primary">In Progress</span></h3> |
| If these are brand new datanodes and Kerberos key tabs are not present at the |
| datanodes, then this request for the datanodes identity certificate is |
| queued up for approval from the administrator(This is work in progress, |
| not committed in Ozone yet). In other words, the chain of trust is established |
| by the administrator of the cluster. |
| <h3>Automatic Approval <span class="badge badge-secondary">In Progress</span></h3> |
| If you running under an container orchestrator like Kubernetes, we rely on |
| Kubernetes to create a one-time token that will be given to datanode during |
| boot time to prove the identity of the datanode container (This is also work |
| in progress.) |
| <p>Once a certificate is issued, a datanode is secure and Ozone manager can |
| issue block tokens. If there is no datanode certificates or the SCM’s root |
| certificate is not present in the datanode, then datanode will register |
| itself and download the SCM’s root certificate as well get the certificates |
| for itself.</p> |
