------------------------------------
Patch for Karaf Cellar trunk.
> Configuration changes not persisted to file when cluster:config-propset is
> executed in a cluster of nodes
> ---------------------------------------------------------------------------------------------------------
>
> Key: KARAF-2477
> URL: https://issues.apache.org/jira/browse/KARAF-2477
> Project: Karaf
> Issue Type: Bug
> Components: cellar-config
> Affects Versions: cellar-3.0.0
> Reporter: Pablo Muñiz
> Attachments: KARAF-2477-cellar-3.0.0.patch
>
>
> Let's suppose a cluster with two nodes: a producer and a consumer, both in
> default group.
> From producer node _cluster:config-propset_ command is executed to change a
> property value in _org.apache.karaf.features_ PID.
> Example:
> {code}
> $ cluster:config-propset default org.apache.karaf.features featuresBoot
> config,cellar
> {code}
> _featuresBoot_ value is changed on both nodes, but is not updated on
> _etc/org.apache.karaf.features.cfg_ file.
> In karaf.log file a message like follows is written :
> {code}
> CELLAR CONFIG: retrieved event ClusterConfigurationEvent [type=0,
> id=org.apache.karaf.features, sourceNode=HazelcastNode [id=localhost:5701,
> host=localhost, port=5701],
> sourceGroup=org.apache.karaf.cellar.core.Group@5c13d641, destination=null,
> force=false, postPublish=false] while groupManager is not available yet
> {code}
> After debugging code I have found that _groupManager_ attribute is not
> initialized in class
> _org.apache.karaf.cellar.config.ConfigurationEventHandler_
> _eventHandler_ bean definition in file
> _config/src/main/resources/OSGI-INF/blueprint/blueprint.xml_ has no
> dependency injection for _groupManager_.
> Comparing this definition with other branches looks like a regression,
> because on branch cellar-2.2.x or cellar-2.3.x this bean definition is
> {code}
> <!-- Cluster Event Handler -->
> <bean id="eventHandler"
> class="org.apache.karaf.cellar.config.ConfigurationEventHandler"
> init-method="init" destroy-method="destroy">
> <property name="clusterManager" ref="clusterManager"/>
> <property name="groupManager" ref="groupManager"/>
> <property name="configurationAdmin" ref="configurationAdmin"/>
> <property name="storage" value="${storage}"/>
> </bean>
> {code}
> Injecting _groupManager_ definition will solve the issue.
