# Set up a secured instance

If you are connecting to HDI secured with Kerberos, you must also perform the following tasks.

1. Configure Kerberos security on the platform, including the Kerberos Realm, Kerberos KDC, and Kerberos Administrative Server.
2. Configure the following items to accept remote connection requests:
   * Name
   * Data
   * Secondary
   * Job tracker
   * Task tracker nodes
3. If you have deployed HDI using an enterprise-level program, set up Kerberos for name, data, secondary name, job tracker, and task tracker nodes.
4. Add user account credentials to the Kerberos database for each Pentaho user that needs access to HDI.
5. Verify that an operating system user account exists on each node in HDI for each user you want to add to the Kerberos database. Add operating system user accounts if necessary.

   **Note:** The user account UIDs should be greater than the minimum user ID value (**min.user.id**). Usually, the minimum user ID value is set to `1000`.
6. Set up Kerberos on your Pentaho machines.See the **Administer Pentaho Data Integration and Analytics** document for instructions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/10.2-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/set-up-the-pentaho-server-to-connect-to-a-hadoop-cluster/additional-configurations-for-specific-distributions-connecting-to-a-cluster/advanced-settings-for-connecting-to-azure-hdinsight-cp/before-you-begin-hdi/set-up-a-secured-instance-hdi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
