> Key: KNOX-2190
> URL: https://issues.apache.org/jira/browse/KNOX-2190
> Project: Apache Knox
> Issue Type: New Feature
> Components: Server
> Affects Versions: 1.4.0

> Assignee: Sandor Molnar
> Priority: Major

> With KNOX-2186, Knox is capable of processing a properties file
> ({{auto-discovery-advanced-configuration.properties}}) which CM generates
> with a list of boolean flags of enabled services. These boolean flags are
> valid to all descriptors (topologies) within all topologies listed in
> {{gateway.auto.discovery.expected.topology.names}}.
> It'd be beneficial to refine this behavior the following way:
> - the monitor would handle different properties files with
> {{auto-discovery-advanced-configuration}} file name prefix (it's also
> recommended that whoever generates these files the file name suffix would be
> the topology name. For instance:
> {{auto-discovery-advanced-configuration-topology1.properties}}).
> - a new property should be introduced in each property file:
> {{gateway.auto.discovery.topology.name}} to indicate the topology name (to
> not to rely on the file name suffix)
> - keep the existing list of boolean flags of service enablement
> - the existing {{gateway.auto.discovery.expected.topology.names}} property
> should be removed (it's no longer useful)
> The monitor then builds a map of properties where the key is the topology
> name and the value is a list of boolean flags (if service X is enabled or
> not) and notifies all {{AdvancedServiceDiscoveryConfigChangeListener}}
> instances when a change is detected.
