[jira] [Created] (IGNITE-4740) Service could be initialized twice
on concurrent cancel and discovery event
Dmitry Karachentsev created IGNITE-4740:
-------------------------------------------
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.
