             Summary: Cloudera Manager integration - advance service discovery handling on topology level
                 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
            Reporter: Sandor Molnar
            Assignee: Sandor Molnar
             Fix For: 1.4.0


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 file 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}}s when a change is detected.
