> Key: KNOX-1117
> URL: https://issues.apache.org/jira/browse/KNOX-1117
> Project: Apache Knox
> Issue Type: Bug
> Components: Release
> Affects Versions: 0.14.0
> Reporter: Phil Zampino
> Assignee: Phil Zampino
> Fix For: 0.15.0
>
>
> 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."
