-------------------------------------------
Summary: Service could be initialized twice on concurrent cancel
and discovery event
Key: IGNITE-4740
URL: https://issues.apache.org/jira/browse/IGNITE-4740
Project: Ignite
Issue Type: Bug
Components: managed services
Affects Versions: 1.8
Reporter: Dmitry Karachentsev
Assignee: Dmitry Karachentsev
Fix For: 2.0
In case of concurrent service cancel and discovery event, for example, applying
continuous query, may cause double init() and execute() service method
invocation.
Fix should consist at least in filtering such DiscoveryCustomEvent in
GridServiceProcessor.TopologyListener.
The best solution is guarantee that despite of any discovery event service
won't be intialized more than once.
