--------------------------------------------
Summary: knoxsso-topology does not get written to disk after
update in Ambari UI
Key: AMBARI-24285
URL: https://issues.apache.org/jira/browse/AMBARI-24285
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.5.0
Environment: HDP 2.6.2.0
Ambari 2.5.0.3
Knox 0.12.0
Reporter: Christopher Jackson
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:
