# Configure View to Use a Distributed Connector or NiFi Ingest

When you set up a system to view documents that you have indexed into the Content component, you need a method to retrieve the original document to convert for viewing. One method for doing this is to use Distributed Connector or NiFi Ingest.

Distributed Connector is a central connector that manages operations across the connectors that retrieve documents from your repositories. Similarly, NiFi Ingest is a central system that manages your connectors, using the Apache NiFi Framework.

In both cases, the Connectors each have access to the document source repository for indexing, so you can use this access for viewing as well. This method simplifies authentication and retrieval for your repositories, and does not require a secondary store of documents for the View component.

This method simplifies authentication and retrieval from your data repositories. However, it requires more network transfer than other viewing methods.

NOTE: For viewing through Distributed Connector or NiFi to work, the connectors must recognize the document reference that you use. OpenText recommends that you use the `AUTN_IDENTIFIER` field as the reference, which all connectors use.

To configure View to use Distributed Connector or NiFi Ingest

1. Open the View component configuration file in a text editor.

2. Find the `[Viewing]` section.

3. Set the following parameters in the `[Viewing]` section:

   `DistributedConnectorHost` | The host name where the Distributed Connector or NiFi component runs.
   `DistributedConnectorPort` | The ACI port for the Distributed Connector, or the port that you have configured the Connector ACI group in NiFi to listen on.

   When you send a `View` action, View checks whether the requested reference is a Web URL or a local file. If it is, View Server retrieves it as normal. If it does not recognize the reference, View sends it to the configured Distributed Connector or NiFi Ingest for retrieval.

4. Save and close the configuration file.

5. Restart the View component for your changes to take effect.

You can use this method only for connectors that support the `View` action.

For Distributed Connector, you must also register the connector in the Distributed Connector, and use a connector group configuration to identify your connectors. For more information about the connector configuration, refer to Knowledge Discovery Expert.
