# Apache HDFS

## Connecting to HDFS

In order to connect, set the following connection properties:

* Host: Set this value to the host of your HDFS installation.
* Port: Set this value to the port of your HDFS installation. Default port: 50070
* UseSSL: (Optional) Set this value to 'True', to negotiate TLS/SSL connections to the HDFS server. Default: 'False'.

## Authenticating to HDFS

There are two authentication methods available for connecting to the HDFS data source, Anonymous Authentication and Negotiate (Kerberos) Authentication.

### Anonymous Authentication

In some situations, HDFS may be connected to without any authentication connection properties. To do so, set the AuthScheme to None (default).

### Kerberos

When authentication credentials are required, you can use [Kerberos](/apprules-r-documentation/appendix/miscellaneous/using-kerberos.md).

## 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.appstrategy.com/apprules-r-documentation/platform/platform-features/system-settings/data-sources/connection-settings/bigdata/hdfs.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.
