> It appears the knoxsso-topology is NOT updated on disk after changed in the
> Ambari UI because of the following code in
> /var/lib/ambari-server/resources/common-services/KNOX/0.5.0.2.2/package/scripts/knox.py:
>
> if params.version_formatted and
> check_stack_feature(StackFeature.KNOX_SSO_TOPOLOGY, params.version_formatted):
> File(os.path.join(params.knox_conf_dir, "topologies", "knoxsso.xml"),
> group=params.knox_group,
> owner=params.knox_user,
> content=InlineTemplate(params.knoxsso_topology_template)
> )
>
> The if condition is preventing the knoxsso.xml from being written as
> indicated in the log of a restart of Knox Service:
