> The topologies included in conf/topologies include hostmap provider config 
> with a comment that needs some work (IMO).
> "Defines rules for mapping host names internal to a Hadoop cluster to 
> externally accessible host names. For example, a hadoop service running in 
> AWS may return a response that includes URLs containing the some AWS internal 
> host name.  If the client needs to make a subsequent request to the host 
> identified in those URLs they need to be mapped to external host names that 
> the client Knox can use to connect.
> If the external hostname and internal host names are same turn of this 
> provider by setting the value of enabled parameter as false.
> The name parameter specifies the external host names in a comma separated 
> list.
> The value parameter specifies corresponding internal host names in a comma 
> separated list."
> Note that when you are using Sandbox, the external hostname needs to be 
> localhost, as seen in out of box sandbox.xml.  This is because Sandbox uses 
> port mapping to allow clients to connect to the Hadoop services using 
> localhost.  In real clusters, external host names would almost never be 
> localhost."
