Docs Text

The values above need to be reflected in each topology descriptor file deployed to the gateway. The gateway by default includes a sample topology descriptor file {GATEWAY_HOME}/deployments/sandbox.xml. The values in this sample are configured to work with an installed Sandbox VM.

<service>
    <role>HDFSUI</role>

Description

The current documentation for proxying the Name Node UI suggests a user should add the following snippet to their topology descriptor file deployed to the Knox gateway:

<service>
<role>HDFSUI</role>
<url>http://sandbox.hortonworks.com:50070/webhdfs</url>
</service>

However, this XML snippet results in a 404 response error and can subsequently be fixed by removing "/webhdfs" and leaving the <DNS>:<PORT> as followed:

<service>
<role>HDFSUI</role>
<url>http://sandbox.hortonworks.com:50070</url>
</service>
