-------------------------------------
Summary: zookeeper discovery sending multiple duplicate endpoint
notifications
Key: DOSGI-176
URL: https://issues.apache.org/jira/browse/DOSGI-176
Project: CXF Distributed OSGi
Issue Type: Bug
Components: Discovery
Affects Versions: 1.5
Reporter: Amichai Rothman
To my understanding of the current behavior, the InterfaceMonitorManager
creates a ZooKeeper watcher (InterfaceMonitor) per scope. The InterfaceMonitor
however monitors ZK nodes according to the objectClass (ignoring scope). When a
ZK node change is detected, the IMs watching that node all trigger IMM's event
handler. But instead of sending out the EndpointListener events corresponding
to the scope for which each IM was created, it loops through all of the
EndpointListener requested scopes and notifies the first matching one. This
effectively causes multiple events to be triggered for the same scope (instead
of one per IM scope), and possibly others to be missed.
