      </p>
      <ol>
        <li>Open the <strong>Connections</strong> page of the {siteNameShort} dashboard.</li>
        <li>Click <strong>Add Connection</strong> to open the <strong>Select Connectors</strong> page.</li>
        <li>
          Click the <strong>{destination ? "Destinations" : "Sources"}</strong> tab and locate
          the <strong>{title}</strong> row.
        </li>
        <li>
          Click the <strong>Configure Connection</strong> icon at the end of that row to open
          the <strong>New Connection</strong> page. This action opens the{' '}
          <strong>Add Connection</strong> dialog box.
          <br />
          <strong>Note:</strong> If the <strong>Configure Connection</strong> icon is not
          available, click the <strong>Download Connector</strong> icon to install
          the {title} connector.
        </li>
        <li>Enter a name for your connection in the <strong>Add Connection</strong> dialog box.</li>
        <li>Click <strong>Add</strong> to open the <strong>Settings</strong> tab for your connector.</li>

## Add the HDFS Connector

<CommonDatasourceAddConnector datasource={datasource} title={pageTitle} destination={false} siteNameShort={siteNameShort} />

## Authenticate to HDFS

After you add the connector, you need to set the required properties.

* **Host:** Enter the host name of your {datasource} server.
* **Port:** Enter the port number for your {datasource} installation. The default port value is **50070**.

{siteName} supports authenticating to {datasource} in several ways. Select your authentication method below to proceed to the relevant section that contains the authentication details.

* [**None**](#none) (default)
* [**Negotiate**](#negotiate)
* [**Token**](#token)

### None

<CommonAuthSchemeNone siteName={siteName} siteNameShort={siteNameShort} datasource={datasource} />

### Negotiate

To connect with Kerberos credentials, specify the following properties:

* **Auth Scheme:** Select **Negotiate**.
* **User:** Enter the username that you use to authenticate to your {datasource} server.
* **Password:** Enter the password that you use to authenticate to your {datasource} server.
* **Kerberos KDC:** Enter the Kerberos Key Distribution Center (KDC) service that you use to authenticate.
* **Kerberos Realm:** Enter the Kerberos realm that you use to authenticate.
* **Kerberos SPN:** Enter the service principal name (SPN) for the Kerberos domain controller.
* (Optional) **Kerberos Keytab File:** Enter the path to the keytab file that contains your pairs of the Kerberos principals and encrypted keys.
* (Optional) **Kerberos Ticket Cache:** Enter the full path to an MIT Kerberos credential cache file. {siteNameShort} uses the specified cache file to obtain the Kerberos ticket that is required to connect to {datasource}.

### Token

To connect with an access token, specify the following properties:

* **Auth Scheme:** Select **Token**.
* **Access Token:** Enter your {datasource} access token.

## Complete Your Connection

To complete your connection:

1. (Optional) For **Path**, enter the {datasource} path for your working directory.
2. Define advanced connection settings on the **Advanced** tab. (In most cases, though, you should not need these settings.)
3. Click **Create & Test** to create your connection.
